A reaction between liquid reactants takes place at 33.0°C in a sealed, evacuated vessel with a measured volume of 40.0L. Measurements show that the reaction produced 6.0g of carbon dioxide gas. Calculate the pressure of carbon dioxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Be sure your answer has the correct number of significant digits.

a) 1 atm
b) 2 atm
c) 3 atm
d) 4 atm
