Question

A canister filled with 3.5 mol of single-atom helium gas has a temperature of

300 K. What is the approximate total internal energy of the gas? (Recall that the equation for kinetic energy due to translation in a gas is: 3/2 nRT; the

equation for kinetic energy due to rotation of a molecule in a gas is: nRT, and R= 8.31 J/(mol.K).)
R= 8.31 J/(mol-K).)
A. 13,100 J
B. 5800 J
C. 15,400 J
D. 8200 J

Answer 1

The answer is C

Please dont get mad at me if this is not right im pretty sure it is
hope this helps!
