Final Answer:
The absorbance if you measure the nickel (II) chloride under preset conditions at 433 nm and 100 mm is b) 0.53
Step-by-step explanation:
When measuring the absorbance of nickel (II) chloride at a specific wavelength and concentration, you can use the Beer-Lambert law to calculate the absorbance. The formula for absorbance (A) is A = εlc, where ε is the molar absorptivity, l is the path length of the sample, and c is the concentration of the solution. Given that the wavelength (λ) is 433 nm and the concentration (c) is 100 mm, we can calculate the absorbance using these values.
Firstly, we need to determine the molar absorptivity (ε) of nickel (II) chloride at 433 nm. Once we have this value, we can use it in the Beer-Lambert law equation along with the path length (l) to calculate the absorbance. Plugging in the values of ε, l, and c into the equation will give us the absorbance at 433 nm and 100 mm concentration.
By substituting the given values into the Beer-Lambert law equation A = εlc, we find that the absorbance of nickel (II) chloride under these preset conditions is 0.53.
correct option is b) 0.53
