Can u help me answer this 2 questions with complete solution please thank you 1. The density of acetonitrile C2H3N is 0.786 g/ml and the density of methanol CH3OH is 0.791 g/mL. A solution is made by dissolving 22.5 ml of CH3OH in 98.7 ml of CH3CN. What is the molarity of the solution? 2. Brass is a substitutional alloy consisting of a solution of copper and zinc. A particular sample of red brass consisting of 80.0% Cu and 20.0% Zn by mass has a density of 8750 kg/m^3 . What is the molality of Zn in the solid solution?
