Answer-Density of acetone = 0.791 g/mLDensity of toluene = 0.87 g/mLmolar mass of acetone = 58.08g/molmolar mass of toluene = 92.14g/molmole ratio = 1:1Volumes required = ?We know that,mole ratio = 1:1i.e. 1 mole of Acetone and 1mole of TolueneAlso,Moles = Mass/Molar MassMass = Moles * MolarMassSo, mass of 1 mole of Acetone = 1 mol* 58.08 g/mol = ...
