The chemist the count the number of particles (Atoms, Molecules or Formula Unit) in a given number of moles of a substance by using following relationship.
Moles = # of Particles / 6.022 × 10²³
Or,
# of Particles = Moles × 6.022 × 10²³
So, from above relation it is found that 1 mole of any substance contains exactly 6.022 × 10²³ particles. Greater the number of moles greater will be the number of particles.

Answer:
subtract
Explanation:
To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.
- The net force is the resultant force acting on a body.
- This resultant force is the single force that will produce the same effects as all given forces.
- When forces are directed oppositely on a body, they are subtracted from each other to find the net force.
