A very simple reaction of acid (HCl) and metal (magnesium) to produce Hydrogen gas and metal salt will provide the volume of gas to evaluate. Students will determine the amount of gas produced at room conditions and then using the combined gas law predict how much gas would have been produced at S.T.P.
