A company dissolves '$\mathrm{x}$' amount of ${\mathrm{CO}}_2$ at $298 \mathrm{K}$ in $1$ litre of water to prepare soda water. $\mathrm{X}=\times {10}^{-3} \mathrm{g}$. (nearest integer)

(Given: partial pressure of ${\mathrm{CO}}_2$ at $298 \mathrm{K}=0.835$ bar. Henry's law constant for ${\mathrm{CO}}_2$ at $298 \mathrm{K}=1.67 \mathrm{kbar}$. Atomic mass of $\mathrm{H},\mathrm{C}$ and $\mathrm{O}$ is $1,12$, and $6 \mathrm{g}{ \mathrm{mol}}^{-1}$, respectively)
