Concept explainers
Interpretation:
Whether trinitrotoluene, TNT, contains 21 atoms per mole or not needs to be determined. If not then correct number of atoms per mol needs to be determined.
Concept introduction:
Trinitrotoluene is an explosive molecule in which there are three nitro groups at 2, 4, 6 positions with respect to toluene.
Answer to Problem 201A
Correct thing about the given statement is that there are 21 atoms in TNT.
Wrong thing regarding the given statement is that there are 21 atoms per mole of TNT.
The correct statement is there are 21 atoms per TNT molecule.
Explanation of Solution
There are Avogadro’s (
Now 1 TNT molecule contains 21 atoms.
So 1 mole TNT must contains
Thus, statement for 21 atoms will be-
There are 21 atoms per TNT molecule.
There are 21 atoms per molecule of TNT.
