How many moles are in 8.30 X 1023 molecules of H2O? with the step

1.38 moles

Explanation: According to Avogadro's law, 1 mole of every substance contains Avogadro number of particles (atoms, molecules or ions) i.e.6.023*10^23  particles.

Given : 1 mole molecule of water contains 6.023*10^23 molecules of water.

6.023*10^23  molecules are present in = 1 mole

 8.30*10^23molecules will be present in =

1/6.023*10^23 ×8.30*10^23=1.38 moles

Thus  molecules is equal to 1.38 moles.
