Answer:
Empirical formula is K₃PO₄.
Explanation:
Given data:
Percentage of K = 55%
Percentage of P = 15%
Percentage of O = 30%
Empirical formula = ?
Solution:
Number of gram atoms of K = 55 / 39.098 = 1.41
Number of gram atoms of P = 15 /30.974= 0.48
Number of gram atoms of O = 30 / 15.999 = 1.88
Atomic ratio:
K : P : O
1.41/0.48 : 0.48/0.48 : 1.88/0.48
3 : 1 : 4
K : P : O = 3 : 1 : 4
Empirical formula is K₃PO₄.
