    Henry's law constant K of \[C{{O}_{2}}\] in water at \[25{}^\circ C\] is \[3.0\times {{10}^{-2}}mol\,{{L}^{-1}}at{{m}^{-1}}\]. The mass of \[C{{O}_{2}}\] present in 100 L of soft drink bottled with a partial pressure of \[C{{O}_{2}}\] of 4 atm at the same temperature is

    A) 5.28 g

    B) 12.0 g

    C) 428 g               

    D) 528 g

    Correct Answer: D

    Solution :

    [d] Moles of \[C{{O}_{2}}\] dissolved \[=K\times {{P}_{C{{O}_{2}}}}\times {{V}_{bottle}}=3\times {{10}^{-2}}\times 4\times 100=12;\] Mass of \[C{{O}_{2}}=12\times 44=528g\]
