Academics

A mouse is placed in a sealed chamber with air at 760.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.60 L, and the temperature is held constant at 293K. After two hours the pressure inside the chamber falls to 719.3 torr. What mass of oxygen has the mouse consumed?
