Question
Calculate the mass ( g ) of the solute acetonitrile and the volume ( L ) of the solvent C6H6 that should be mixed to produce 4.72 kg of a solution that is 1.34 m acetonitrile.

molality = moles/kg solvent
moles = grams/molar mass.
The above two equations are needed.
equation 1.
You are given molality = 1.34 and kg solvent is 4.74 kg. Solve for moles.
Then use equation 2.
Plug in moles and molar mass, solve for grams.
moles = grams/molar mass.

Isn't 4.72Kg the mixed solution and the solvent?
