How do you find the number of particles?
- The number of particles in a substance can be calculated using:
- Number of particles = Avogadro constant × the amount of substance in mol.
- Calculate the number of water molecules in 0.5 mol of water.
- Number of water molecules = Avogadro constant x amount of substance in mol.
How many particles are there in a mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).
