    2g of \[{{O}_{2}}\] at \[{{270}^{o}}C\] and 760 mm of Hg pressure has volume :

    A)  1.4 L           

    B)  2.8 L

    C)  11.2L          

    D)  22.4 L

    Correct Answer: A

    Solution :

    Key Idea: Molecular mass in gram = 22.4 L at STP. Given mass of \[{{O}_{2}}=2\,g\] at \[{{27}^{o}}C\] and 760 mm Hg                 32 g of \[{{O}_{2}}=22.4\,L\] at STP \[\therefore \] 2 g of \[{{O}_{2}}=\frac{22.4}{32}\times 2=1.4\,L\]
