Solution: Various data can be used to find the composition of an alloy (a metallic mixture). Show that calculating the mass % of Mg in a magnesium-aluminum alloy (d = 2.40 g/cm3 ) using each of the following pieces of data gives the same answer (within rounding):a) a sample of the alloy has a mass of 0.263 g (d of Mg = 1.74 g/cm3 ; d of Al = 2.70 g/cm3 );b) an identical sample reacting with excess aqueous HCl forms 1.38×10−2 mol of H2;
