If 0.600 mol of a nonvolatile nonelectrolyte are dissolved in 3.70 mol of water, what is the vapor pressure ph2o of the resulting solution? the vapor pressure of pure water is 23.8 torr at 25 ? c .

To get the vapor pressure of the resulting solution, we use the Raoult’s Law:

Psolution = (χsolvent) (P°solvent)

1st: Calculate the mol fraction of the solvent. In this case, water is the solvent.

χsolvent = 3.7 mol / (3.7 mol + 0.6 mol)

χsolvent = 0.86

2nd: Calculate the vapor pressure.

Psolution = (0.86) (23.8 torr)

Psolution = 20.48 torr

d they tend to lose electrons and become cations.

explanation:

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
