`CO_(2)` gas is bubbled through water during a soft drink manufacturing process at 298 K. If ` CO_(2)` exerts a partial pressure of 0.835 bar then x m mol of ` CO_(2)` would dissolve in 0.9 L of water. The value of x is ________ . (Nearest integer)
(Henry's law constant for `CO_(2) ` at 298 K is `1 . 67 xx 10^(3)` bar )

Text Solution

Verified by Experts

The correct Answer is:
25
According to Henry.s law
`P_("gas")=X_("gas")xxK_H`
`X_("gas")=(0.835)/(1.67xx10^3)=5xx10^(-4)`
`X_("gas")=(n_("gas"))/(n_("gas")+n_(H_2O))~~(n_("gas"))/(n_(H_2O))`
`n_("gas")=5xx10^(-4)xx900/18=0.025 ` mole or 25 m mol
