Question
A sample of gas consists of μ1 moles of monoatomic molecules, μ2 moles of diatomic molecules and μ3 moles of linear triatomic molecules. The gas is kept at a high temperature. What is the total number of degrees of freedom?
Options
[3μ1 + 7(μ2 + μ3)] NA
[3μ1 + 7μ2 + 6μ3] NA
[7μ1 + 3(μ2 + μ3)] NA
[3μ1 + 6(μ2 + μ3)] NA
Solution
[3μ1 + 7(μ2 + μ3)] NA
