Evaluate the vapor pressure of the methanol solution

Reference no: EM13527339

An ideal solution is formed from a mixture of the nonvolatile solute urea, CO(NH2)2, and methanol, CH3OH. The vapor pressure of pure methanol at 20°C is 89 mmHg. If 4.9 g of urea is mixed with 31.0 g of methanol, calculate the vapor pressure of the methanol solution.

A. 77 mmHg
B. 20 mmHg
C. 82 mmHg
D. 6.9 mmHg
