Answer :
Answer: 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
