Glycerin (c3h8o3) is a nonvolatile liquid. what is the vapor pressure of a solution made by adding 154 g of glycerin to 316 ml of h2o at 40.0°c? the vapor pressure of pure water at 40.0°c is 55.32 torr and its density is 0.992 g/cm3.

Explanation:

According to given:

Upon the formation of solution the vapour pressure will be reduced since we have one component of solution as non-volatile.

moles of water in the given quantity:

moles of glycerin in the given quantity:

Now the mole fraction of water:

Since glycerin is non-volatile in nature so the vapor pressure of the resulting solution will be due to water only.

i don't know that i agree with that but what's the question ?
