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

You want to determine the concentration of NaCl in a water. In preliminary analysis, it appears to be saline water with a NaCl content of approximately 4%. Should you dilute the sample if your titrant has a concentration of 0.1 M and you want to spend 25 mL of sample? Solution: You must dilute approximately ten times, taking 10 mL of sample and making up to 100 mL. In this way, 17.20 mL of titrant will be spent.

Procedure A: Molarity (M=g/MM/L) Step 1. Place one-eighth of a teaspoon (this weighs approximately 0.5 grams) of NaCl (table salt) in the graduated cylinder provided. Then add distilled water to that graduated cylinder until the level of the water reaches 45.00 mL. Mix thoroughly about 1 minute. Pour solution into a somewhat clear cup. Remember what this looks like for Procedure B. Questions: Is this a saturated solution? Why or why not? Take a picture and insert a picture (compress your image) of your solution here. Save this solution for Step 2. Calculations: Determine the Molarity of this solution using the formula M = g/MM/L. You know the grams (one-eighth of a teaspoon weighs approximately 0.5 grams), look up the Molar Mass of NaCl, and convert your mL to L to solve the problem.) Show your calculations for Molarity here.

A 0.1 g amine-containing compound is dissolved in water then diluted to 100 mL. You subject it to spectroscopic analysis, in order to get the concentration of amine in this compound. Next, you get 1 mL of the previously diluted sample then dilute it again to 250 mL for measurement. Then, you fill 3/4 of a 1-cm cuvette with this diluted sample, and you run an analysis using an AAS. The recorded absorbance is 0.545 at 410 nm. What is the molecular weight of the compound? (The molar absorptivity is 1.23 x 104 cm-1 mol-1 L.)

of a 0.9% solution of sodium chloride (NaCI), we would weigh 0.9 g of NaCl (solute) and dissolve it in some distilled wate (solvent). When the salt is totally dissolved, enough distilled water is added to make a final volume of 100 mL. When measuring solutions in a cylinder, pipette, or volumetric flask, be sure to hold the calibrated glassware at eye level to read the bottom line of the curved surface of the liquid (the meniscus). Volumetric glassware should be used fo solution preparation; calibrated Erlenmeyer flasks or beakers too inaccurate. The size of calibrated glassware chosen shoul equal to or just slightly larger than the volume desired so tha error of measurement will be minimal.
