The Transmittance of a Sample Is the Ratio of the Intensity

Multiple Choice

The transmittance of a sample is the ratio of the intensity of radiation transmitted to the intensity of the incident radiation. The molar absorption coefficient of the [Cu(NH₃) ₄]²⁺ complex ion in aqueous solution is 50 dm³ mol^-1 cm^-1 at a wavelength of 590 nm. Determine the transmittance when light of this wavelength passes through an aqueous solution of the ion of molar concentration 0.100 mol dm^-3 and path length 1.00 cm.

B) 10^-2
C) 10^-6
D) 10^-4
