Question

What is the density of $C0_2$ at $27 \,{}^{\circ}C$ and $2.5 $ atm pressure?

• A. $5.2 \, g$ $L^{-1}$
• B. $6.2 \, g$ $L^{-1}$
• C. $7.3 \, g$ $L^{-1}$
• D. $4.46 \, g$ $L^{-1}$

Answer 1

Answer: (D)

From ideal gas equation,
$d=\frac{PM}{RT}$ =$\frac{2.5\times44}{0.0821\times300}$ = $4.46 \,g$ $L^{-1}$
