Glycerin, C3H8O3, is a nonvolatile liquid. What is the vapor pressure of a solution made by adding 164 g glycerin to 3.38 mL H2O at 39.8 C? The vapor pressure of pure water at 38.8 C is 54.74 torr and its density is 0.992 g/cm^3. Does this have to do with Henry's Law? Can someone help explain this to me? Thanks.

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

Before it was launched, a helium-filled balloon had a pressure of 201 kpa at a temperature of 27°c. at an altitude of 15,000 m, the pressure had decreased to 2.5 kpa and the temperature had dropped to -14 °c. the volume of the balloon increased to 59.3 m3. what is the original volume of the balloon? 13 m3 0.85 m3 0.077 m3 1.17 m3

Explain how to convert from one unit to another in the metric system.
