Calculate the mass of paradichlorobenzene (M=147.01g/mol) that should be added to 20.00 ml of cyclohexane (d = .779g/ml) to make a .05 molal solution. I did this problem but i dont know if i did it correctly. first i found the mass of cyclohexane by using m=dv. (.05moles solute/kg solvent)(15.58g)(1kg/1000g)(147.01g/mol) = .11g does this seem correct. I am not sure. Thanks.
