A student needs a 15% hydrochloric acid solution for a chemistry lab. How much 20% hydrochloric acid should she mix with 60 mL of 5% acid to get a 15% solution? a) Use a TABLE to clearly and completely organize the information. Be sure to correctly label EACH row and column. If necessary, use variable names that make sense in the context of the problem (do not usex or y). b) Use your answer to part a to set up a linear equation in one variable that can be solved to determine the how many mL of 20% hydrochloric acid are needed. The equation must pull directly from the table c) Rewrite and solve your equation from part b. You must solve a single-variable linear equation

Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?
If a solution is made by adding 8g of (NH4)2SO4 to a 100 ml volumteric flask and enough water is added to bring the total volume to 100ml, what would the density of the solution be? This is a straightforward question but I just wanted some clarification. When we bring the total volume to 100ml, does that mean we added 100ml of water? Will the mass of the water be 100 g regardless of the amount of solute added?
I need to make a solution containing 0.025 grams per liter. However, I do not want to weigh 0.025 grams and put this in one liter of solvent. I want to make a stock solution of 0.25 grams in 500 ml of solvent and take a unknown aliquot and dilute this in 500ml of solvent instead of 1000 ml of solvent. How do I calculate the volume of aliquot from the stock solution to achieve a final concentation of 0.025 grams per liter? What is the proper equation(s) required to figure out the proper aliquots required?
Come up with a dilution scheme starting from 1000 μg/mL Mn stock solution so that the concentration of permanganate in the solutions just prior to measurement (after Step B.6.) are: 7.5, 15.0, 22.5, 30.0 and 37.5 μg/mL MnO4-. Carefully read the units!
Case: A prescription for calls for compounding 60 mL of an oral solution for patient A. This oral solution contains 45 mg of salicylic acid. The pharmacist decides to weigh this on a balance with a minimum weighable quantity of 120 mg and dissolve it an appropriate solvent to prepare the solution. Answer the following questions to explain how you will use the liquid measurement aliquot method to obtain the correct amount of salicylic acid to prepare this solution. When making this preparation, you want to minimize the amount of salicylic acid that is wasted. The prescription is as follows: Rx Salicylic acid 45 mg Cherry flavor solution 5 mL Ora-Syrupee qs 60 mL What is the target amount of salicylic acid for the liquid aliquot that will be used to make the 60 mL oral solution? What is the maximum volume of the liquid aliquot can be used to make this preparation? If you weigh 120 mg of…
Use only 1 decimal point (X.X) for all atomic weights. What will be the final molarity of 5.00 mL of 14.0 M HNO3 dilluted to 700.0 mL?
Today the only form of liquid acetaminophen on the market has a concentration of 160 mg acetaminophen per 5.0 mL. How would you instruct parents of an infant to give a total of 40 mg of acetaminophen to their infant? Your directions should be clear, not lead to the confusion caused by the physician in the case study, and include the volume of liquid acetaminophen they should give their son. Please show how you calculated the volume needed to provide 40 mg of acetaminophen.
CHEMISTRY (Please write the complete solution legibly. No long explanation needed. Answer in 2 decimal places. Box the final answer.) A laboratory is well-stocked with 1.0 M H2SO4 and 6.0 M H2SO4, but 500 mL of 2.5 M H2SO4 areneeded for an experiment. Unfortunately, the water supply has been temporarily cut off, so the 2.5M solution must be made from the existing solutions. How many milliliters of 1.0 M and 6.0 MH2SO4 must be mixed in order to prepare 500 mL of 2.5 M solution?
A student dissolves 2.135 g of potassium chloride in enough water to make 100.00 mL solution. Th student then pipettes 10.00 mL of this solution into a 250.00 mL volumetric flask then fills the flask up to the calibration line with water. What is the concentration of potassium chloride in the 250.00 mL volumetric flask?
Water and acetonitrile, CH3CN, are miscible (can be mixed in any proportions). However, whenwater and acetonitrile are mixed, the volumes are not additive (the total volume of the resultingsolution is not equal to the sum of the pure liquid volumes). For example, when 100.0 mL ofwater and 100.0 mL of CH3CN(l), are mixed at 20 °C, the total volume of the solution is 192.0mL,not 200.0 mL.a. Provide an explanation for this phenomenon.b. Calculate the molarity, molality and mol fraction of CH3CN in a solution preparedby mixing 100.0 mL of water and 100.0 mL of CH3CN(l) at 20 °C. The total volume of themixture is 192.0 mL and the densities of water and acetonitrile are 0.998 g/mL and 0.782g/mL, respectively, at this temperature.c. When 70.0 g H2O and 190.0 g CH3CN(l) are mixed, to resulting solution has adensity of 0.860 g/mL at 20 °C. Calculate the volumes of the pure liquid samples and thesolution, and show that the pure liquid volumes are not additive.
A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.
Professor X mixed two solutions in a test tube and observed that the mixture was warm. He also tried to mix 50-ml each of the solutions in a 100-ml volumetric flask and found out that the total volume was less than 100 ml. He only has water, methanol, ethanol, and acetone in his table. From the following choices, what solutions did Professor X mix? a.acetone and water b.water and methanol c.acetone and ethanol d.methanol and ethanol
