Question #195353

hydrogen gas effuses through a porous container 8.97-times faster than an unknown gas. Estimate the molar mass of the unknown gas.

Expert's answer

MM(H_{2}) = 2.016 g/mol

"\\frac{Rate_A}{Rate_B} = \\sqrt{\\frac{MM_B}{MM_A}} \\\\\n\n8.97 = \\sqrt{ \\frac{MM_B}{2} } \\\\\n\n(8.97)^2 = \\frac{MM_B}{2.016} \\\\\n\nMM_B = (8.97)^2 \\times 2.016 = 162.21 \\;g\/mol"

Answer: 162.21 g/mol
