Using the transmittance formula T(%) = 10^(2 - A), what is the transmittance when absorbance A equals 0?

Explanation:
When absorbance is zero, no light is absorbed and all of it passes through. Transmittance, expressed as a percent, reflects this complete passage of light. Using the given formula, plug in A = 0: T(%) = 10^(2 - 0) = 10^2 = 100. So the transmittance is 100%. This aligns with the idea that zero absorption corresponds to full transmission. Note that the relation can also be written as T(%) = 100 × 10^(-A), which shows how transmittance decreases as absorbance increases.
