Interpretation:
The method of calculation of mole ratio in a chemical compound needs to be explained.
Concept introduction:
The chemical compound is composed of more than one different type of elements. There is a certain mole ratio of each element in the chemical compound which represents the empirical and molecular formula.
Answer to Problem 71SSC
- Calculate moles of each element from mass and molar mass.
- Divide with least moles to get the mole ratio of each element.
Explanation of Solution
Given information:
The mole ratio of a chemical compound can be calculated.
To calculate the mole ratio of a chemical compound:
- Consider mass % as mass in grams and calculate moles of element with the help of molar mass
- Calculate the moles of each element in least whole number
It will give mole ratio of each element which are involved in the formation of the chemical compound.
- Calculate moles of each element from mass and molar mass.
- Divide with least moles to get the mole ratio of each element.
