rate of effusion is inversely proportional to square root of molar mass
so,
rate of H2 / rate of Ne = sqrt (molar mass of Ne / molar mass of H2)
rate of H2 / (1.86*10^-4) = sqrt(20.2/2)
rate of H2 / (1.86*10^-4) = sqrt(10.1)
rate of H2 / (1.86*10^-4) = 3.178
rate of H2 = 5.91*10^-4 mol/h
Answer: 5.91*10^-4 mol/h
