A sample of Zn metal reacts completely with of an excess of HCl. The hydrogen gas produced is collected over water at 25.0C using an arrangement similar to that shown on slide 298. The volume of the gas is 7.80L, and the pressure is 0.980 atm. Calculate the amount of Zn metal in grams consumed in the reaction. (Vapour pressure of water at 25C = 23.8 mmHg).
