# Problem: How many moles of H2 can be produced from y grams of Al in magnesium-aluminum alloy? The molar mass of Al is 26.98 g/mol.Express your answer in terms of y to four decimal places (i.e., 0.5000y).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.

How many moles of H2 can be produced from y grams of Al in magnesium-aluminum alloy? The molar mass of Al is 26.98 g/mol.

Express your answer in terms of y to four decimal places (i.e., 0.5000y).

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.
