When 4.65 g of a nonelectrolyte solute is dissolved in 475 mL of water at 27 C, the resulting solution exerts an osmotic pressure of 931 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?

For the M I got .0265 M.
For moles I got .129 mols.
For molar mass I got .585 g/mol.

Can someone check this for me?
