Hi, I've a chem assignment in which I've to calculate the stray light, Ps as a percentage of the incident light, Po. Given the apparent absorbance A(app) 0.047, concentration of the solution 2.00 x 10pwr-6, cell length of 1cm, activity coefficients = 1. I calculated the transmittance to be A = -log T , where T = 0.8974 T = P + Ps / Po + Ps = 0.8974 T = P / Po = 0.8974 I'm stuck after that with 2 unknowns in the equation. Could someone advice me on this? Thanks a lot!
