How many particles are in 12 moles of H2O

7.224 × 10²⁴ particles

Explanation:

The number of particles in a substance can be calculated by multiplying the number of moles of the substance by Avogadro's Number ~ 6.02 × 10²³ particles/mol.

∴ # particles in 12 mol of water = 12 mol × 6.02 × 10²³ particles/mol

                                                   = 7.224 × 10²⁴ particles
