A 0.250 g sample of a magnesium-alumnium alloy dissolves completely in an excess of HCL(aq). When the liberated H2(g) is collected over water at 29 deg C and 752 torr, the volume is found to be 307 mL. The vapor pressure of water at 29 deg C is 30.0 torr. How many moles of H2 can be produces from x grams of Mg in Magnesium-aluminum alloy? The molar mass of Mg is 24.31 g/mol. Express your answer in terms of x to four decimal places. Thanks for your help in advance!
