thanks!

When 4.21 g of a nonelectrolyte solute is dissolved in 165 mL of water at 26 degree C, the resulting solution exerts an osmotic pressure of 909 torr. What is the molar concentration of the solution? How many moles of solute are in the solution? What is the molar mass of the solute?

Solution

pv=nrt

[909/760]/0.0821*299=c

c=0.0487 m/L

No of moles=0.0487*0.165=8.03*10-3

molar mass=4.21/8.03*10-3
