    The mass of \[\text{112}\,\text{c}{{\text{m}}^{\text{3}}}\]of \[\text{C}{{\text{H}}_{\text{4}}}\] gas at STP is:

    A)  0.16 g                                  

    B)  0.8 g

    C)  0.08 g                                  

    D)  \[1.6\,g\]

    Correct Answer: C

    Solution :

    At STP \[\text{22400}\,\,\text{c}{{\text{m}}^{\text{3}}}\]of \[\text{C}{{\text{H}}_{4}}=12+4=16\,gm\,(C{{H}_{4}})\] At STP \[\text{112}\,\text{c}{{\text{m}}^{\text{3}}}\]of \[C{{H}_{4}}=\frac{16\times 112}{22400}=0.08\,gm.\]
