Question 45.e of 45 A sample of helium is initially at 565 torr in a volume of 2.85 L. At 24.7 °C you found the density of He to be 0.122 g/L and the density of Ar to be 1.22 g/L even though both samples had the same number of moles. Which one of the following best explains why the densities are different? A B D Argon is a heavier atom than helium, so it has more mass in the same volume occupied by the gas. Argon is a larger atom than helium so it occupies more volume. An argon atom is more dense than a helium atom. The densities are different only because of rounding.
