Chemistry question below?

A saturated solution of ammonium nitrate, NH4NO3, in methanol, CH3OH, contains 3.42 g of NH4NO3 in 20.0 mL of methanol at 20 C. The density of methanol at this temperature is 0.7914 g/ mL. Calculate the solubility of NH4NO3 in methanol in units of g solute/ (100 g sovent).

20mL of methanol have a weight of 0.7914*20 =15.828g

15.828g contain 3.42g NH4NO3

100g contain 3.42*100/15.838 =21.61g solute/100g methanol
