Question

potassium nitrate (KNO3) and potassium phosphate K3PO4 are two potash fertilizers which one of them is better fertilizer

Answer 1

Potassium nitrate kno3

Answer 2

Molecular weight of potassium phosphate K3PO4 = 3*39+31+4*16

Percentage Composition of K = (39*3/212) * 100 = 55.18percent of K

Molecular weight of Potassium Nitrate KNO3 = 39+14+3*16 = 101

Percentage Composition of K = (39/101)*100 = 38.61percent of K.

Answer - K3PO4 : PERCENTAGE OF K = 55.18percent more than KNO3 percentage of K = 38.61percent.
