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 $58\mathrm{.}0cm$ wide and $69\mathrm{.}6cm$ high. The maximum safe pressure inside the vessel has been measured to be $7\mathrm{.}20$MPa.

For a certain reaction the vessel may contain up to $26\mathrm{.}2kg$ of sulfur tetrafluoride 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.
