Explanation:
Here we are given that the percentage of ,
- Calcium = 24.7%
- Hydrogen = 1.20%
- Carbon = 14.8%
- Oxygen = 59.3%
And we need to find out the Empirical formula of the compound .
- Firstly divide the given percentage by the atomic mass of the compound . Here this is followed in the fourth column of the table , which will give the relative number of atoms .
- Secondly , divide the value obtained by the smallest value among them .Say if we got the relative number of atoms as 4 , 3 and 2 , then divide all three numbers by 2 . ( followed in 5th column below .)
- Finally write the Empirical formula of the compound by writing the ratio obtained as the subscript of respective compounds .
Let's make a table ,
Therefore we got the ratio of Ca , H , C and O as 1:2:2:6 . Therefore the Empirical formula of the compund will be ,
