Aim: To investigate the volume of 1 mole hydrogen molecules at room temperature. Plan: In this experiment, different masses from a 25 cm length of magnesium ribbon will be allowed to react with hydrochloric acid in a glass cylinder. The volume of hydrogen gas produced will be measured with the glass syringe and noted down on a result table. The formula for this reaction is: Mg(s) + HCL(aq) --> MgCl2(aq) + H2(g) From this equation, 1 mole of magnesium gives rise to 1 mole of hydrogen. But in order to calculate what volume 1 mole of hydrogen gas occupies, we have calculate the volume of 1 mole of H2 obtained from our results. Apparatus: * 25 cm of magnesium ribbon * Hydrochloric acid * Gas syringe * Glass tube with rubber bung and tube * A smaller glass tube for magnesium * Retort stand and clamp * Measuring cylinder or beaker * Safety goggles * Electronic balance * Ruler * Tweezers * Sand paper Safety...
