Question

At a temperature of $273\, K$ and pressure of $2$ atm the weight of $305 \, mL$ of a diatomic gas is $1\,g$ . What is the weight of one atom? ( $N$ is the Av. no.)

• A. $\frac{16}{\text{N}}$
• B. $\frac{32}{\text{N}}$
• C. $16 \, N$
• D. $32 \, N$

Answer 1

Answer: (A)

Calculate $M \, =\frac{R T w}{P V}$
$Wt$ . of one atom $=M / \left(N \times 2\right)$
