The d is for delta. As in delta T change in temperature. When dividing M and ρ it seems as though grams cancels out and you're left with 1/cm-3*mol. If i instead divide ρ by M we are left with cm-3*mol which is V x n. I don't see where this can be put into the formula though, is there a formula...
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.
