Containers A and B have same gases. Pressure, volume and temperature of A are all twice that of B, then the ratio of number of molecules of A and B are

Answer

B

Explanation

According to gas law
`PV= nRT, n=(PV)/(RT)`
`(n_(A))/(n_(B))=((P_(1)V_(1))/(RT_(1)))/((P_(2)V_(2))/(RT_(2))),(n_(A))/(n_(B))=(P_(1)V_(1))/(T_(1))xx(T_(2))/(P_(2)V_(2))`
`(n_(A))/(n_(B))=(2Pxx2V)/(2T)xx(T)/(PV), (n_A)/(n_(B))=(2)/(1)`
