A block of dry ice (solid CO2, density = 1.56 g/mL) of dimensions 25.0 cm 25.0 cm 25.0 cm is left to sublime (i.e., to pass from the solid phase to the gas phase) in a closed chamber of dimensions 4.00 m ´ 5.00 m 3.00 m. The partial pressure of carbon dioxide in this chamber at 25°C will be (R = 0.08206 L atm/mol K, 1 atm = 760 mmHg):
