2.17 x 10²³molecules
Explanation:
Given parameters:
Number of moles of water = 0.36moles
Unknown:
Number of molecules in a water sample = ?
Solution:
A mole of substance is the amount of substance that contains the Avogadro's number of particles which is 6.02 x 10²³ particles.
The particles are molecules, formula units, number of protons, neutrons, electrons, e.t.c;
Since 1 mole of any substance = 6.02 x 10²³ molecules
0.36 moles of water = 0.36 x 6.02 x 10²³ = 2.17 x 10²³molecules
