Question

Consider a sample of helium and a sample of neon, both ${at30}^{0}C$ and $1.5atm$. Both samples have a volume of $5.0L$ . Which statement concerning these samples is not true?

• A. Each sample contains the same number of atoms of gas
• B. Each sample weighs the same amount
• C. Each sample contains the same number of moles of gas
• D. The density of the neon is greater than the density of the helium

Answer 1

The correct option is B Each sample weighs the same amount

Option - B is not true.

$\Rightarrow$ because both samples have equal volume means same number of atoms at $1.5$ atm & ${30}^{0}C$.

$\Rightarrow$ The density of $Ne$ gas is higher than helium.

Each sample weighs the same amount is not true.
