Question

If a commercial water sample containing yellow dye has a percent transmitter, % t, of 43, what is the molar concentration of the yellow dye in the vitamin water?

Option 1: 0.43 M
Option 2: 4.3 M
Option 3: 0.043 M
Option 4: 43 M

Answer 1

The molar concentration of the yellow dye in the vitamin water cannot be determined based on the given information.

Step-by-step explanation:

To determine the molar concentration of the yellow dye in the vitamin water, we need to convert the percent transmittance (% t) to absorbance (A). Absorbance is related to concentration by Beer's Law: A = εlc, where ε is the molar absorptivity, l is the path length, and c is the concentration. Since we don't have the molar absorptivity or the path length, we cannot directly calculate the concentration from the given information.

Therefore, none of the options provided (0.43 M, 4.3 M, 0.043 M, 43 M) can be determined as the correct molar concentration of the yellow dye in the vitamin water based on the information given.

Additional information regarding the molar absorptivity or the path length would be needed to calculate the molar concentration accurately.
