Metals such as magnesium and zinc react with dilute sulfuric acid to give hydrogen, according to the equation: M (s) + H2SO4 (aq) -------> MSO4 (aq) + H2 (g) When 5.00 g of a mixture of powdered magnesium and zinc were dissolved in diluted sulfuric acid, 0.284 g of hydrogen gas was collected. What was the composition of the mixture of Mg and Zn expressed as percent by mass? If the volume of acid used was 100 mL, what were the final molar concentrations of MgSO4 and ZnSO4?
