plaees When taking the logarithm of a num after the decimal as signifi with a % transmitta ber, the resulting log should have as many cant figures in the original number. For example, a sample nce of 26.3 (3 significant figures) has an absorbance of A-2-log 26.3m2-1 log 26.3-2-1.420 -0.580 (3 places after the decimal) each solution has been calculated, the concentration of t .
