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 10.0 cm wide and 12.0 cm high. The maximum safe pressure inside the vessel has been measured to be 8.10 MPa. For a certain reaction the vessel may contain up to 0.170 kg of sulfur hexafluoride 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: 10
