Answer:

= 0.2 molecule

Explanation:

Gram atomic mass of water (H2O) = (1×2+16) gm = (2+16) gm = 18 gm

∴ Number of molecules in 18 gm of water = 1 mol ecule

∴ Number of molecule in 1 gm of water = 1/18 mol ecule

∴ Number of molecule in 3.6 gm of water = (1/18 x 3.6)molecule = 0.2 molecule

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
