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.

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?
