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 L'atm 0.0832 mol·K L'atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error =|1.389 (b) For the statements below, identify the possible source(s) of error for this student's trial. The student uses the barometric pressure for the lab to calculate R. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student does not clean the zinc metal with sand paper. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it.
