Calculate the volume ( mL ) of the solute C2H5OH and the mass ( g ) of the solvent diethyl ether that should be mixed to produce 3.46 kg of a solution that is 1.31 m C2H5OH.

volume ( mL ) of the C2H5OH

mass ( g ) of the (C2H5)2O

Molar Mass (g/mol)
C2H5OH 46.07
(C2H5)2O 74.12

Density ( g/mL )
C2H5OH 0.7893
(C2H5)2O 0.7138

diethyl ether

I got 249.5ml
and 3263g

is that right?
