일반물리학 1 — The Kinetic Theory of Gases: Problem 39

39 A container holds a mixture of three nonreacting gases: 5.61 mol of gas 1 with \(C_{V1} = 12.0 \text{ J/mol} \cdot \text{K}\), 4.22 mol of gas 2 with \(C_{V2} = 12.8 \text{ J/mol} \cdot \text{K}\), and 3.20 mol of gas 3 with \(C_{V3} = 20.0 \text{ J/mol} \cdot \text{K}\). What is \(C_V\) of the mixture?
