molarity = # mols/L of solution.
molality = # mols/kg solvent.
g toluene = density x volume
g benzene = density x volume
mols benzene = g/molar mass
Post your work if you get stuck.
A solution is made by mixing 35.0 mL of toluene C6H5CH3 d=0867gmL with 125.0 mL of benzene C6H6 D=0874gmL. Assuming that the volumes add upon mixing, the molarity (M) and molality (m) of the toluene are?
Find M and m
