i am stuck on this problem from school

A solution is made by mixing 30.0 mL of toluene C6H5CH3d=0.867gmL with 130.0 mL of benzene C6H6d=0.874gmL . Assuming that the volumes add upon mixing, the molarity (M) and molality (m) of the toluene are

1 answer

How many grams of toluene do you have? How many moles is that?

What is the mass of the benzene?

Molarity=molesToulene/volumesolutioninLiters

molality=molesToulene/kgOfSolvent
