🤓 Based on our data, we think this question is relevant for Professor Al-Nidawy & Wang's class at University of Windsor.
How many moles of H2 can be produced 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 (i.e., 0.5000x).
A 0.250-g sample of a magnesium-aluminum alloy dissolves completely in an excess of HCl(aq). When the liberated H2(g) is collected over water at 29 °C and 752 torr, the volume is found to be 319 mL. The vapor pressure of water at 29 °C is 30.0 torr.
