I appreciate all help I can get!!

Calculate the osmotic pressure of each of the following aqueous solutions at 20.00 degree C: 2.25 M methanol (CH3OH) 9.17mMMgCI2 38.0 mL of glycerol (C3H8O3) in 250.0 mL of aqueous solution (density of glycerol = 1.265 g/mL) 15.8 g of CaCl2 in 350 mL of solution

Solution

a) 54.45 atm

b) 0.662 atm

c) 50.27 atm

d) 29.34 atm

osmotic pressure = i M R T
