To find the number of water molecules in 2.46 mL of water at 4°C, we use the formula:
Number of molecules = (Volume of water in mL) * (Density of water in g/mL) * (Avogadro's number) / (Molar mass of water in g/mol)
Number of molecules = (2.46 mL) * (1.00 g/mL) * (6.022 × 10^23 molecules/mol) / (18.015 g/mol)
Number of molecules ≈ 8.25 × 10^22 molecules
