Question

the number of molecules in 3.6 g H2O is​

Answer 1

Answer:

Hey, The answer is 1.2044 × 10²³

Explanation:

No. Of Moles= Given Mass / Molar Mass

                     = 3.6/(1×2+16)

                     = 3.6/18= 0.2 Moles

No. Of Particles(Molecules)= No. Of Moles × Avogadro Constant

                                             = 0.2×6.022×10²³

                                              =1.2044 × 10²³ Number of Molecules are present                                                                                           in 3.6g of H₂O
