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 $37\mathrm{.}0cm$ wide and $44\mathrm{.}4cm$ high. The maximum safe pressure inside the vessel has been measured to be $5\mathrm{.}60$MPa.

For a certain reaction the vessel may contain up to $4\mathrm{.}73kg$ of chlorine pentafluoride gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Be sure your answer has the correct number of significant digits.

temperature: $C$
