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 21.0 cm wide and 25.2 cm high. The maximum safe pressure inside the vessel has been measured to be 6.70 MPa.

For a certain reaction, the vessel may contain up to 0.639 kg of boron trifluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits.
