Chemistry

Answer:

2.00

Explanation:

From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.

Let the rate of effusion of Helium be R1

Let the rate of effusion of Methane be R2

Let the molecular mass of Helium be M1

Let the molecular mass of Methane be M2

Hence;

R1/R2 = √M2/M1

R1/R2 = √16.0294/4.0026

R1/R2 = 2.00
