A sample of zinc metal reacts with an excess of hydrochloric acid (hydrogen chloride) via a single displacement reaction. All of the zinc reacts, and the hydrogen gas is collected over water at 17C; the barometric pressure is 750mmHg. The level of water inside the tube containing the gas is 31.0cm above the water level outside the tube. If the volume of gas in the tube is 22.1 mL, how many grams if zince were there in the sample?
