You have a material that is 1550 cells/L in water and you want to dilute it in the following sequence in a 3 tube dilution. Tube 1 is 15 mL and a 1/15 dilution; Tube 2 is 10 mL and and a 1/5 dilution; tube 3 is 5 mL and a 1/10 dilution. How much of what goes in each tube. What is the concentration of all the tubes?
For 0.250 L of aqueous solution with a density of 1.00 g/mL containing 13.7 mg of pesticide, express the concentration of pesticide in ppm and ppb.
It is known that acid content has a major effect on theflavor of vinegars, but most cheaper vinegars are diluted similarly to 5% acidity Wt./vol. % is equivalent to gsolute per 100mL solution (so 5% is equivalent to 5 g acid/100 mL solution). a.) First, calculate the approximate molar concentration of acetic acid in the 5% wt./vol vinegar. b.) Next, calculate the expected molarity of acetic acid in the solution upon dilution by a factor of 5. Thank you!
25 ppm of CaCO3 was found in the water sample obtained on the lake in the nearby town.Calculate the moles of CaCO3 having a molar mass of 100.09 g/mol in 10 liters of water samplesolution having a density of 997 kg/m3. (Ans.: 24.95 moles CaCO3)
In this station, you will find a sample of table salt; the chemical formula of table salt is NaCl. Using the balance, weigh out 6.00 g of NaCl and dissolve in 50 mL of deionized (d.i.) water. Once com-pletely dissolved, add additional d.i. water to make the final volume of solution 100.0 mL. What is the mass percent NaCl in the solution? What is the molarity of the solution
A solid sample contains unknown amounts of potassium and magnesium chloride and moisture. 1.193 g of the sample is dissolved in water and the solution is diluted to 250.00 mL. 25.0 mL of the sample is allowed to pass through an H + -saturated cation exchanger, the eluate consuming 22.03 mL of a 0.100 M NaOH solution. The moisture content of the sample was determined to be 5.22%. Calculate the % by weight of potassium and magnesium chloride in the sample.
8. Find the final concentration of ethanol as a percent (v/v) when 30 mL of ethanol 50 % (v/v), 60 mL of ethanol 70 % (v/v), and 40 mL of ethanol 95 % (v/v) are mixed together.
Prepare 0.1 M solutions of NaOH and 0.1 M ethyl acetate using high-purity distilled water. So, weight desired amount of NaOH and ethyl acetate and dissolved in dH2O to prepare stock solution in equal molarity. Mw (NaOH) = 40.0 g/mol , Mw (EtOAc)= 88.1 g/mol, Density(EtOAc): 0.898 g/cm3
When drinking water is disinfected with chlorine, an undesired byproduct, chloroform (CHCl3), may form. Suppose a 70-kg person drinks 2 L of water every day for 70 years with a chloroform concentration of 0.08 mg/L (the drinking water standard). Potency factor for chloroform = 6.1 x 10-3 (mg/kg-day)-1 The upper-bound cancer risk for this individual. a. 0.545 b. 5.45x10-6 c. 5.45x10-4 d. 5.45x10-10 e. 14x10-6 If a city with 300,000 people in it also drinks the same amount water described in the above question, how many extra cancers per year would be expected?

A powdered crude sample of Na2CO3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr.What is the %purity of the sample to the nearest whole number?
