CO2 gas is bubbled through water during a soft drink manufacturing process at 298 K. If CO2 exerts a partial pressure of 0.835 bar then x m mol of CO2 would dissolve in 0.9 L of water. The value of x is ____________. (Nearest integer)
(Henry's law constant for CO2 at 298 K is 1.67 $\times$ 103 bar)
Answer (integer)
25
Solution
From Henry's law<br><br>P<sub>gas</sub> = K<sub>H</sub>.X<sub>gas</sub><br><br>0.835 = 1.67 $\times$ 10<sup>3</sup> $\times$ ${{n(C{O_2})} \over {{{0.9 \times 1000} \over {18}}}}$<br><br>$\Rightarrow$ n(CO<sub>2</sub>) = 0.025<br><br>Millimoles of CO<sub>2</sub> = 0.025 $\times$ 1000 = 25
