Gas A is about 9 times heavier than gas B. Gas A was placed in a standard balloon and tested to effusion speed. The gas was found to have a effusion speed of k. What is the expected effusion speed of gas B? Assume that the mass of gas A per mol is M g/mol.

     

    A

    k/3

    B

    3k

    C
