A sample of Mg metal containing some MgO as impurity was dissolved in 125 mL of 0.1N H_(2)SO_(4). The volume of H_(2) evolved at 27.5^(circ)C and 1 atmwas 120.0 mL. The resulting solution was found to be 0.02N with respect to H_(2)SO_(4). Calculate the weight of sample dissolved and the % by weight of pure Mg metal in sample. Neglect any change in volume.
