The percentage of calcium phosphate in ore = 55. 9% so it means each 100g of ore contains 55.9 g of calcium phosphate
The formula of calcium phosphate = Ca3(PO4)3
As per molecular formula each mole of calcium phosphate contains three moles of phosphorous
mass of each mole of calcium phosphate = 310 g
for 31 g of P we need = 310 /3 g of calcium phosphate
= 103.33 g of calcium phosphate
for 1 g of P we need = 103.33 / 31 g of calcium phosphate = 3.33 g
So for 1000g of P we need = 3.33 X 1000g of calcium phosphate
= 3333.3 g of calcium phosphate
now for 55.9 g of Calcium phosphate we need = 100 g of ore
so for 3333.3 g of calcium phosphate we need = 100 X 3333.3 / 55.9 g
= 5963.03

Assuming the complete question is;
Consider the balanced equation below;
4NH3 + 3O2 = 2N2 +6H2O
What is the mole ratio of NH3 to N2;
From the balanced equation; the mole ratio of NH3 to N2 is 4:2.
The mole ratio is the ratio of moles of one substance to the number of moles of another substance in a balanced equation. In the above equation; 4 moles of ammonia requires 3 moles of oxygen to produce two moles of nitrogen and six moles of water.
Answer:
atoms have a positive nucleus and negative electrons,an atoms electron configuration the outermost electrons determines how the atom can interact with the other atoms and atom forms another atom for sharing electrons.
