    A bottle of cold drink contains 200 mL liquid in which\[C{{O}_{2}}\]is 0.1 molar. Suppose\[C{{O}_{2}}\]behaves like an ideal gas, the volume of the dissolved C02 at STP is

    A)  0.224 L                                

    B)  22.4 L

    C)  0.448 L                                

    D)  44.8 L

    Correct Answer: C

    Solution :

                     Number of moles of\[C{{O}_{2}}\]in 200 mL solution \[=molarity\times volume\](in L)                 \[=0.1\times \frac{200}{1000}\] \[=0.02\] Volume of 0.02 mole of\[C{{O}_{2}}\]at STP \[=22.4\times 0.02\] \[=0.448L\]
