60 cm of hydrogen diffused through a porous membrane in 10 minutes. The same volume of gas G diffused through the same membrane in 37.4 minutes. Determine the relative molecular mass of

Answer 1

rate 1 = H2 = 60/10 = ?
rate 2 = G = 60/37.4 = ?

(rate1/rate2) = sqrt(MMG/MMH2) where MMG is molar mass G and MMH2 = molar mass H2.
You know molar mass H2. The only unknown is MMG.

Answer 2

60 cm of hydrogen diffused through a porous membrane in 10 minutes. The same volume of gas G diffused through the same membrane in 37.4 minutes. Determine the relative molecular mass of g (h equal to 1)
