Asked by Milo

you reacted magnesium with a hydrochloric acid aqueous solution and hydrogen gas was produced. Let's say that you collected the gas given off by the reaction and measured it's pressure as 102.1 kPa. If the vapor pressure of water is 16.2 kPa at this temperature, then what is the pressure of the hydrogen gas?
