    200 mL of \[{{N}_{2}}\] at 25° C and 250 mm of Hg are mixed with 350 mL of \[{{O}_{2}}\]at 25° C and 300 mm of \[Hg\] in a vessel of capacity 300\[mL\]. Calculate the final pressure of mixture at 25° C.

    A) 326.0 mm Hg       

    B) 516.67 mm of Hg

    D) 608.0 mm of Hg

    Correct Answer: B

    Solution :

    If the gases are mixed at same temperature \[{{p}_{1}}{{V}_{1}}+{{p}_{2}}{{V}_{2}}={{p}_{3}}{{V}_{3}}\] \[250\times 200+300\times 350={{p}_{3}}\times 300\] \[{{p}_{3}}=516.67\]mm of Hg.
