Question

A compound contains 43.4% sodium, 11.3% carbon and 45.3% oxygen. Determine empirical formula.

Answer 1

a chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms in the molecule CH2O is the empirical formula for glucose

or

In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound.[1] A simple example of this concept is that the empirical formula of sulphur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S2O2 This means that sulfur monoxide and disulfur dioxide, both compounds of sulfur and oxygen, will have the same empirical formula. However, their chemical formulas, which express the number of atoms in each molecule of a chemical compound, may not be the same.
