Explain what amount of hydrogen measured at stp

Reference no: EM13668745

The purity of a sample containing zinc as well as weighing 0.198 g is determined by measuring the amount of hydrogen formed when the sample reacts with an excess of hydrochloric acid. The determination illustrates the sample to be 84.0% zinc. Explain what amount of hydrogen measured at STP was obtained?
