Homework Statement
There is a monatomic gas held at a constant pressure of P = 1.48-atm, it also has a molar mass M = 16-g/mol and density ρ =1.9 × 10-3-g·cm-3. Find the total internal energy of 1-mol of this gas.
Homework Equations
U = Q + W
E = nCvT
PV = nRT
The Attempt at a Solution
I have tried E = 3/2nRdT but I am unsure as to how I could use molar mass and density to find anything that can be subbed into the equations. I tried dividing M and ρ cm-3/mol but I'm not sure were to go from there.
