EXPERIMENT : GRAVIMETRIC ANALYSIS OF PHOSPHORUS IN PLANT FOOD

Aim: To determine the amount of phosphorus in a commercial plant food

 

I want the Calculations for this experiment

Observations: Mass of plant food (original sample) = 2 g Weight of Filter Paper = W1 = 0.87 g Weight of Filter paper + Precipitate = W2 = 2.85 g Weight of Precipitate Wz - Wi = 2.85 – 0.87 = 1.98 Table 1: Measurement of Conductance. Trial Plant Food (g) Amount of P (g) % P Calculations: 2 g of soluble plant food yields (W2-W:) g of MGNH4PO4.6H2O [M9NH4PO4.6H2O] 245 g 31 g (Wz-W1) g of MGNH4PO4.6H2O = 'X' g of P Amount of P = Percent phosphorous in the original sample: gP % P = (- x 100 'g original samnple
