Calculate the mass % of N and P.
Determine which bag of fertilizer, KNO3 or LiPO2 will support greater plant growth.
For KNO3
MM = 102.1032g/mol
Atomic mass of N = 14.0067 g/mol
% by mass = %
Mass of N in 10kg of KNO3 =
For LiPO2
MM = 69.9136g/mol
Atomic mass of P = 30.973762g/mol
% by mass = %
Mass of P in 12kg of LiPO2 =
Conclusion 12kg of LiPO2 contains more of the important nutrient hence will support more growth than 10kg of KNO3
