What is the pressure exerted by 43 mol of nitrogen in a 65 L cylinder at 5°C?

Answer 1

Approx. #15*atm#

We employ the equation for ideal gas.

#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#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
