A 5.34 g sample of an aluminum alloy is re-
acted with hydrochloric acid to produce alu-
minum chloride and hydrogen gas. At a tem-
perature of 298 Kelvin and a pressure of 1.03
atm, a volume of 1.53 L of hydrogen gas is col-
lected. Assuming that the hydrochloric acid
only reacts with the aluminum in the sam-
ple, what is the percent of aluminum in the
alloy sample? (Solid aluminum reacts with
hydrochloric acid to produce aluminum chlo-
ride and hydrogen gas).
