A sample X\text{X}X of helium gas (molar mass = 4.0 g mol-1) has a mass of 6.0 g and is at an absolute temperature TTT. The total random kinetic energy of the molecules in sample X\text{X}X is EEE.
Another sample Y\text{Y}Y of argon gas (molar mass = 40 g mol-1) has a mass of 30 g and is at an absolute temperature 3T3T3T.
Both gases behave as ideal gases. What is the total random kinetic energy of the molecules in sample Y\text{Y}Y?
23E\frac{2}{3} E32E
6E6 E6E
32E\frac{3}{2} E23E
15E15 E15E
