Approx. #15*atm#

Explanation:

We use the Ideal Gas equation:

#P=(nRT)/V# #=# #(43*molxx0.0821*L*atm*K^-1*mol^-1xx278K)/(65*L)# #~=# #15*atm#

Do the units cancel to give units of #"atmospheres"#? If they don't then I have made a mistake. The only pitfall in this question, is the requirement to use absolute temperature.

#"Degrees Kelvin"# #=# #""^@"Celsius"+273#
