Answer:
Answer: 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.
