A common way to make hydrogen gas in the laboratory is to place a metal such as zinc in hydrochloric acid. The hydrochloric acid reacts with the metal to produce hydrogen gas, which is the collected over water. Suppose a student carries out this reaction and collects a total of 168.3 mL of gas at a pressure of 744 mmHg and a temperature of 25 degree C. What mass of hydrogen gas in mg does the student collect?
