Question #99892
Gas Y effuses half as fast as O2. What is the molar mass of gas Y? answer in g/mol
Expert’s answer
According to Graham’s law, (r1/r2)2=M2/M1r1 and r2 are the rates of effusion and M1 and M2 are the molar masses of the two gases. M1 = 32 g/molThen,(1/2)2= 32/M of y1/4=32/M yM y = 32•4 = 128 g/mol Have a nice day 🙂
