Answer:
NaO
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
.
Given data:
Percentage of sodium = 59.0%
Percentage of oxygen = 41%
Empirical formula = ?
Solution:
Number of gram atoms of Na = 59.0 / 23 = 2.6
Number of gram atoms of O = 41 / 16 = 2.6
Atomic ratio:
Na : O
2.6/2.6 : 2.6/2.6
1 : 1
Na : O = 1:1
Empirical formula is NaO.
