Calculate the molar mass of butane. Butane's rate of diffusion is 3.8 times slower than that of hleium.
Pie

Answer:

58 g/mol

Explanation:

According to Graham's law, the rate of diffusion of a gas (r) is inversely proportional to the square root of its molar mass (M). Butane's rate of diffusion is 3.8 times slower than that of helium, that is, rButane = rHe/3.8, or rHe/rButane = 3.8. Then,

\frac{rHe}{rButane} =3.8=\sqrt{\frac{M(Butane)}{M(He)} } =\sqrt{\frac{M(Butane)}{4.00g/mol} } \\M(Butane)=3.8^{2} \times 4.00g/mol\\M(Butane)=58g/mol
