Q58 / 200 · NEET 2023 (Manipur) · Chemistry

The correct option in which the density of argon (Atomic mass $=40$ ) is highest

  • Correct answer
    A
    $0^{\circ} \mathrm{C}, 4 \mathrm{~atm}$
  • B
    $273^{\circ} \mathrm{C}, 4$ atm
  • C
    STP
  • D
    $0^{\circ} \mathrm{C}, 2 \mathrm{~atm}$

Solution

$\mathrm{PV}=\mathrm{nRT}$ $\begin{aligned} P & =\frac{n}{V} R T \\ P & =\frac{d}{M} R T\end{aligned}$ $P=\frac{d}{M} R T$ $\frac{P M}{R T}=d$

Hence, the correct answer is option: 'A'.
