To determine the molar mass of the unknown gas, we use Graham's Law of Effusion where it relates the effusion rates of two gases with their molar masses. It is expressed as r1/r2 = √M2/M1. We calculate as follows:
Let 1 = argon gas
2 = unknown gas
r2 = 0.91r1
r1/r2 = 1/0.91
1/0.91 = √M2/M1 = √M2/40
M2 = 48.30 g/mol
