A Solution Contains 5.0 Grams Of Toluene (C7H8) And 225 Grams Of Benzene (C6H6) And Has A Density Of .876 G/ml. Calculate The Molarity Of The Solution? I Don’t Know How To Set This Problem Up, Please Help.

Molarity=number of moles of solute/volume in dm3
Molecular mass of toluene=92g/mol
Number of moles=5/92=0.0543moles
Volume=mass/density
Mass of solution=5+225=230g
Density=.876g/ml
Volume=230/.876=262ml=262cm3
Volume=.262dm3
So
Molarity=0.0543/.262=0.2M
