Expert Solution
Step 1: Relation between rate of effusion and molar mass

Answer:

Rate of effusion of a gas is inversely proportional to the square root of its molar mass, therefore

straight r subscript 2 over straight r subscript 1 equals square root of straight M subscript 1 over straight M subscript 2 end root
