(a)
Interpretation:
The chemical notation
Concept Introduction:
The composition of a chemical compound can be presented in a very precise was with the use of chemical formula. Chemical formula uses chemical symbols of the elements that is present in the compound and numerical subscripts that represent how many number of atoms of each element is present in the compound.
(a)
Answer to Problem 1.75EP
Explanation of Solution
Given chemical notation is
The total number of atoms present in the chemical formula is found by summing up the subscript present in the chemical formula.
Therefore, there are six atoms in the given chemical formula.
