A 1mL sample of water that is known to contain 200.0 ppm nitrite was diluted to 100 mL. A 10mL aliquot of that solution was treated with reagents to form a colour, and after dilution to 100mL was found to have absorbance = 0.175. A 10mL sample of aquarium water was treated with reagents to form a colour, and after dilution to 100 mL was found to have an absorbance of 0.162. calculate the concentration in ppm of nitrite in the aquarium water.
