Answer:
The number of moles of 4.25g water is 0.24 moles.
Explanation:
Given that,
mass of H₂O = 4.25g
molar mass of H₂O = 2×1 + 16 = 18 g.mol⁻¹
Number of moles = given mass / molar mass
Moles of H₂O = mass of H₂O / molar mass of H₂O
⇒ = 4.25 g / 18 g.mol⁻¹
⇒ = 0.236
⇒ ≈ 0.24 mol.
Hence, the number of moles of 4.25g water is 0.24mol.
