Count the number of atoms of each element in the following compounds.
Multiply with the 5 in front gives us 1 5 5 fe. There are 2 c but since there s a 3 outside the bracket it means 2 3. And finally because there s that 5 in front of the entire molecule total atoms is 2 3 5 30 c. Teach your students how to count the number of atoms in a molecule using this great detailed worksheet this worksheet guides students through the following topics what is a subscript and what does it tell us what is a coefficient and what does it tell us what do the brackets in a chemical formula.
