At 20 degrees celsius the vapor pressure of dry ice is 56.5atm. If 10 g of dry ice (solid CO2) is placed in an evacuated 0.25 L chamber at a constant temperature of 20 degrees celsius, will all of the solid

sublime?

Is the answer no? I don't know if this is right, but I used the ideal gas law to see what the pressure would be in the chamber and got 21 atm. I compared that to the 56.5 atm, but I'm not sure what the answer is because it's lower.
