1. A 5.85 g sample containing only MgO and CuO is placed in a 5.00 L container. The container is filled with CO₂ to a pressure of 740 torr at 20°C. After the reaction has gone to completion, the pressure inside the flask is 290 torr at 20°C. What is the mass percent of MgO in the mixture? Assume that only MgO reacts with CO2.
