Hi, I seem to have forgotten how to do this...
50cm2 x 2.87ug cm2 hr-1 = C x 21L/h
I know how to find the answer for C by rearranging but having diffilculties in what the unit should be.
Can someone help? thanks.
edit: I think I done it: ug/cm3

You have cm2 * μg * cm2 * hours-1 on the left hand side, which is of dimension (length)4 * (mass)1 * (time)-1, and on the right hand side you have C * L * h-1, which (I presume) has dimension [C] * (length)1 * (time)-1, for some unknown [C]. Dimensions on the left and right must be the same, so equate these two, and solve for [C] just like you'd solve for any unknown.
