What is the mass percent of aluminum in the alloy

A 4.00 g sample of an aluminum-copperalloy reacts with excess hydrochloric acid. The 2.81 L of H2(g) produced is collected over water at a barometric pressure of 758.4 mmHg and 19°C. What is the mass percent of aluminum in the alloy?(aluminum reacts but copper does not react)
Note: The pressure of water vapour at 19°C is 16.48mmHg

2Al(s) + 6 HCl(aq)---->2 AlCl3(aq) + 3H2(g)
