(Q27) The hydrogen gas evolved in a reaction between solid zinc and hydrochloric acid has been collected over water. The volume of water displaced is equal to 0.684 L. Given that the gas was collected at a temperature of 30.0°C and the atmospheric pressure was 736 torr, what mass (in mg) of hydrogen gas was collected? (3 sf)
