A sample of hydrogen (2.02 g/mol) effuses through a porous container about 8.85 times faster than an unknown gas. Estimate the molar mass of the unknown gas.
Answer in units of g/mol

  • Chemistry - ,

    (rate1/rate2) = sqrt(M2/M1)
    M2 and M1 are molar masses.
    rate1 and rate2 are not given but the ratio is; therefore, make up a number for the rate1 and use the ratio to determine rate 2.
