JEE Main & Advanced Chemistry States of Matter Question Bank Ideal gas equation and Related gas laws

  • question_answer 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 \[C{{O}_{2}}\] at STP is                [CBSE PMT 1991]

    A)                 0.224 litre            

    B)                 0.448 litre

    C)                 22.4 litre              

    D)                 2.24 litre

    Correct Answer: B

    Solution :

               No. of moles of \[C{{O}_{2}}\]present in 200 ml solution                    = molarity ´ Volume (in lt.) \[=0.1\times \frac{200}{1000}=.02\]                                 Volume of 0.02 mole of \[C{{O}_{2}}=22.4\times .02lt.\]\[=0.448lit.\]
