Question

The density of $C{O}_2$ gas at ${27}^{0}C$ and $1atm$ pressure is _____ (gram/litre).

• A. $1.78$
• B. $1.52$
• C. $1.96$
• D. $1.20$

Answer 1

The correct option is A $1.78$

$PV=nRT$

$\Rightarrow 1\times V=\frac{m}{44}\times 0.0821\times 300$

$\Rightarrow d=\frac{m}{V}$

$\Rightarrow d=\frac{44}{0.0821\times 300}$

density= $1.78g/Litre$
