A student experimentally determines the gas law constant, r, by reacting a small piece of magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. Based on experimentally collected data, the student calculates r to equal 0. 0832 l·atm mol·k. Ideal gas law constant from literature: 0. 08206 l·atm mol·k (a) determine the percent error for the student's r-value.
