question mark

the number of particles given by n = – D [ n2 – n1 ] x2 – x1 are crossing a unit area perpendicular to x- axis in unit time n1 and n2 are the number of particles per unit volumne for the values of xmeant to be x1 and x2 . What is the dimensional formula od diffusion constant D?

dimensions of N= dimension of D*[dimensions of(n2-n1)/dimensions of(x2-x1)
1/L^2T=dimensions of D*[L^-3/L]
dimensions of D=L/L^-3*L^2T=>Dimensions of D = L^2/T=L^2/T=L^2T^-1
