Two part question. Thank you in advance

15.853 g of a non-volatile solute is dissolved in 340.0 g of water.
The solute does not react with water nor dissociate in solution.
Assume that the resulting solution displays ideal Raoult's law behaviour.
At 70°C the vapour pressure of the solution is 230.47 torr.
The vapour pressure of pure water at 70°C is 233.70 torr.
Calculate the molar mass of the solute (g/mol).

Now suppose, instead, that 15.853 g of a volatile solute is dissolved in 340.0 g of water.
This solute also does not react with water nor dissociate in solution.
The pure solute displays, at 70°C, a vapour pressure of 23.37 torr.
Again, assume an ideal solution.
If, at 70°C the vapour pressure of this solution is also 230.47 torr.
Calculate the molar mass of this volatile solute.
