1.	According to Graham's law, at a given temperature the ratio of diffusion r_A/r_B of gases A and B is given by (where P and M are pressures and molecular weights of gases A and B respectively)
Answer» `(P_A/P_B)(M_A/M_B)^(1//2)` `(M_A/M_B)(P_A/P_B)^(1//2)` `(P_A/P_B)(M_B/M_A)^(1//2)` `(M_A/M_B)(P_B/P_A)^(1//2)` SOLUTION :`(P_A/P_B)(M_B/M_A)^(1//2)`
