calculate the number of molecule in 3.6g of H2O
Answers
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
