What is the temperature of the hydrogen gas in K? Use the information you solved for above with the Ideal Gas Law to determine the amount (moles) of hydrogen produced. (This is not your final calculation, so keep one extra sig fig here or you'll round far from the real answer. Remember the leading zero rule.) Use the moles of hydrogen you just calculated and the balanced chemical reaction equation to determine the mass of the magnesium used in the reaction. Make sure your answer has the proper number of sig figs based on the starting data. Show or explain how you determined the number of significant figures the answer should have.
