What is Gas Law Constant Evaluation Experiment about?

This experiment aims to determine the gas constant, R, through the reaction of magnesium and hydrochloric acid to produce hydrogen gas. The student weighed magnesium ribbons, reacted it with hydrochloric acid while measuring temperature, pressure and volume of hydrogen gas produced. Calculations using the ideal gas law yielded an experimental R value of 5.585 × 10-3 L atm mol-1 K-1, which has a large percentage error compared to the theoretical value. Sources of error include impurities on the magnesium and
