Question

How do you write the complete ionic equation and net ionic equation for ammonium chloride and copper (II) sulfate in water?

If your aspirin sample has an absorbance of 0.500 in a 1.00 cm cell, what will be its absorbance in a 1.50 cm cell. What would be the percent change in the absorbance if you used the larger cell and didn’t factor in the change in path length? The equation is y = 0.148X-0.058

I found the absorbance, which was about 0.3139. I just don’t understand the second part of the question.
