What volume (in mL) of 30.0% hydrogen peroxide solution is required to provide the mass required in question 8 above? Mass=10.2g of a 30% hydrogen peroxide soltuion. Density of 30.0% H2O2 = 1.11 g/mL Answer with 3 sig figs.
Please help I'm not sure how to solve these. A solution is prepared by dissolving 20g of NaCl (f.w.= 58.44 g mol^-1), a nonvolatile solute, in enough water (m.w. = 18.02 g mol^-1) to result in exactly 1 L of solution at 25 C. The density of the solution is 1 g mL ^-1. How do you calculate freezing point of the solution as well as vapor pressure and the osmotic pressure? I understand boiling point.
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?

Hello, Can you please answer these three short answer style questions for me? Thank you!
You are a chemist and FBI crime scene investigator and find a sealed bag containing a suspicious white substance. The substance turns out to be a powder containing fentanyl (C22H28N2O, 336.470 g/mol) and lactose (C12H22O11) 342.298 g/mol). To find out exactly how much fentanyl was in the bag, you use a 100.0 mL volumetric flask to dissolve 1.000 g of the white powder in water. The osmotic pressure for the solution at laboratory temperature, 21.7 °C, is 538.2 mmHg. What percent of the white powder is fentanyl?
