Using the ideal equation of state
A reaction between liquid reactants takes place at -1.0 °C in a sealed, evacuated vessel with a measured volume of 20.0 L. Measurements show that the reaction produced 47. g of dinitrogen difluoride gas.
Calculate the pressure of dinitrogen difluoride 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.
pressure: atm
