Question

nass of solute M, can be calculated.
Problem 2.4: A solution is prepared by
dissolving 394 g of a nonvolatile solute
in 622 g of water. The vapour pressure of
solution is found to be 30.74 mm Hg at
30 °C. If vapour pressure of water at 30 °C
is 31.8 mm Hg, what is the molar mass of
solute?
