Dry ice (solid CO2) has been used as a mine explosive in the following manner. A hole is drilled into the mine wall, filled with dry ice plus a small charge of gunpowder, and then plugged. The gunpowder is lit with a fuse, vaporizing the CO2 and building up an explosively high pressure within the hole. Use each of the following correlations to estimate the pressure that will develop if 5.00 g of dry ice is placed in a 50.0-mL hole and heated to 1000 K:

(a) The ideal gas equation of state,

(b) The compressibility-factor equation of state, and
