At 20 degrees celsius the vapor pressure of dry ice is 56.5
atm. If 10 g of dry ice (solid CO2) is placedin in an evacuated 0.25 L chamber at a constant temperature of 20 degrees celsius, will all of the solid sublime?
PV = nRT
Solve for n at the conditions listed, convert to grams CO2, and compare with 10 g you started with.
