An ionic compound is found to contain 10.9% magnesium, 31.8% chlorine and 57.3% oxygen. what is the empirical formula for this compound?

The empirical formula is MgClO₈.

Explanation:

To find the empirical formula, which is the minimum integer ratio between the atoms in a compound, we have to follow some steps.

Step 1: Divide each percentage by the atomic mass of the element

Step 2: We divide all the numbers by the smallest

In this case, the smallest number is 0.449

Step 3: We incorporate these numbers as the atomicities in the empirical formula

The empirical formula is MgClO₈.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
