Concept explainers
Interpretation:
Whether the percent composition of all the pure samples for a given compound is same or not should be explained.
Concept introduction:
The mass percentage of each type of the atoms present in a compound is termed as percentage composition.
Answer to Problem 160A
Yes, the composition of the elements in a pure compound have the same percent composition.
Explanation of Solution
Molecular formula or Chemical formula represents the type and number of atoms present in the molecule using atomic symbol and numerical subscripts.
The chemical composition of all the elements present in a pure compound is definite thus, the chemical formula for a pure substance and its percent composition remains same always.
For example, water is composed of 2 atoms of hydrogen and one oxygen atom thus, the percent composition of hydrogen and oxygen by mass will always be 2.016 and 15.999 g.
