Count the atoms of each element, and the atoms in all, in one formula unit of:
- ammonium carbonate,
- iron(III) sulphate,
- potassium phosphate,
Need a reminder? The key ideaShow
A chemical equation shows the reactants on the left and the products on the right. State symbols: solid, liquid, gas, dissolved in water. Gases such as oxygen, hydrogen and chlorine are written as , , . A number after a bracket multiplies everything inside it.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) N: . H: . C: . O: . In all: .
Step 2. (b) Fe: . S: . O: . In all: .
Step 3. (c) K: . P: . O: . In all: .
Answer: (a) atoms. (b) atoms. (c) atoms.
