CYNAT2 marksNeeds review
The absorption maxima of two dyes X and Y are 520 and 460 nm, respectively. The absorbance data of these dyes measured in a 1 cm path length cell are given in the table below.
Dye solution | Absorbance at 460 nm | Absorbance at 520 nm |
|---|---|---|
X (9 mM) | 0.144 | 0.765 |
Y (12 mM) | 0.912 | 0.168 |
Mixture of X and Y | 0.700 | 0.680 |
The concentration of Y in the mixture is ________ mM. (Up to two decimal places)
