Final answer:
In chemistry, you multiply the coefficient times the subscript to determine the total number of atoms in a molecule or compound.
Step-by-step explanation:
In chemistry, when determining the total number of atoms in a molecule or compound, you need to multiply the coefficient (the number in front of the formula) by the subscript (the number written below and to the right of an element symbol) to determine the number of atoms.
For example, in the compound H2O (water), there are 2 hydrogen atoms (H) and 1 oxygen atom (O). The coefficient (2) is multiplied by the subscript (2), resulting in a total of 4 hydrogen atoms and 2 oxygen atoms in the molecule of water.
So, the statement is true. When determining the total number of atoms in a molecule or compound, you multiply the coefficient times the subscript.
