Answer:
Empirical formula is MnO₂
Explanation:
Given data:
Percentage of Manganese = 63%
Percentage of oxygen = 37%
Empirical formula = ?
Solution:
Number of gram atoms of Mn = 63 / 55 = 1.1
Number of gram atoms of O = 37/ 16 = 2.3
Atomic ratio:
Mn : O
1.1/1.1 : 2.3/1.1
1 : 2.1
Mn : O = 1 :2
Empirical formula is MnO₂.
