What is the mass percentage of aluminum in this alloy

Reference no: EM13171504

A 0.250 g sample of a magnesium-aluminum alloy dissolves completely in an excess of HCl (aq). When the liberated hydrogen gas is collected over water at 29 degrees celsius and 752 torr, the volume is found to be 343 mL. The vapor pressure of water at 29 degrees celsius is 30.0 torr. What is the mass percentage of aluminum in this alloy?
