Reference no: EM13342794

A sample of mercury(II) oxide is placed in a 10.00L evacuated container and heated until it decomposes entirely to mercury metal and oxygen gas. The container is then cooled to 22.5 degrees C. One now finds that the gas pressure inside the container is 0.871atm. What mass of mercury(II) oxide was originally placed into the container?
