In order to detrmine P content, 5.0 g of flour ashed (weight of ash 0.02g), the ash diluted to 200ml, then 20ml taken & diluted to 50ml and 10ml from the 50ml is taken into 100 ml followed by reading the absorbance after adding reagents at 650 nm, and the concentration was detrmined from standard curve equation (y= 0.345x) to be 2 ppm. The concentration of Pin mg/100 g is: O a. 400 b. 300 c. 100 d. 200
