Posted by kat on Friday, February 21, 2014 at 3:36pm.

By how much will the vapor pressure of water decrease if a solution at 40.0C is produced by dissolving 16.0212 g of K3PO4 (formula mass = 212.30 g/mol) with 40.8480 g of water. The vapor pressure of pure water at this temperature is 55.30 mmHg. If the solute is ionic, assume that it is completely ionic!
we use Raoults law but i don't know how to use the g given
