A container contakns 5.3*10^12 particles of H2O how many moles is this

Answer: 8.804 * 10⁻¹² moles

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. Therefore to find the number of moles based on the number of particles, you would divide the number of moles by Avogadro's Number.

Since # of particles of H₂O = 5.3*10¹² particles

then # of moles of H₂O = 5.3*10¹² particles : 6.02 * 10²³ particles/mol

= 8.804 * 10⁻¹² moles
