The purpose of this lab was to determine the standard molar volume of hydrogen gas. In order to measure the standard molar volume, we needed the volume of H2, which we measured at 0.035 L inside the burette. Also, we needed the number of moles of hydrogen; we calculated this by doing the mole to mole ratio of Magnesium and Hydrogen while using the balanced equation. The number of moles turned out to 0.00144. Then, dividing the volume of H2 by the number of moles of H2 , I calculated the standard molar volume of H2 to be 22.2L. First plausible source of error can be that we did not use exactly 10ml of HCL, instead, we used 9 ml. Secondly, we filled the burette to 53ml, instead of 50ml. And thirdly, there was an air bubble at the bottom of the
