A piece of solid CO2, with a mass of 6.2g is placed in a 4L otherwise empty container at temp of 21C?

if 6.2g solid CO2 were placed in the same container but it already contained air at 740 torr, what would be the partial pressure of CO2? in atm





What would be the total pressure in the container aster the CO2 vaporizes? in atm
