By mole concept, we know that 1 mole molecule of any substance has avogadro number of molecules(6.022*10^23). So we need to find the moles of water in 1 L of water or 1000mL of water. Taking the density of water to be 1g/mL, 1000mL of water= 1000g water

Answer:55.55Na
Explanation: given,
Mass = 1litre
1l=1000grams
Number of atoms =(given mass) ÷ (gram atomic weight)
Weight of H2O=(2×1.008)+16
=18.016
=18
Number of atoms =(given mass) ÷ (gram atomic weight)
Number of atoms=1000÷18
=5.55------
