A 20.0 % by mass solution of a compound (molar mass 42.5g/mol) in water at 25°C has a density of 1.16 g/ml. calculate the vapor pressure
of this solution knowing that the vapor pressure of water at this
temperature is 23.7 mmHg and its molar mass is 18.0 g/mol.
a) 21.4 mmHg
b) 242 mmHg
c) 18.5 mmHg
d) 22.6 mmHg
e) 20.1 mmHg
