A standard containing 1.0 ppm NO3-N was treated with a reactive agent to give the absorbance of the 0.30 at 600 nm. A sample was analysed in same manner, which gave absorbance of o.15 at the same wavelength. Quantify the level of NO3-N in this sample: 0.45 ppm NO3 O 0.75 ppm NO3 0.50 ppm NO3 non of above
