A reaction between liquid reactants takes place at 31.0°C in a sealed, evacuated vessel with a measured volume of 20.0L. Measurements show that the reaction produced 13.g of sulfur hexafluoride gas.

Calculate the pressure of sulfur hexafluoride gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits.

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures wide and high. The maximum safe pressure inside the vessel has been measured to be . For a certain reaction the vessel may contain up to of sulfur hexafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction.
