The number of water molecules present in a drop of water (volume 0.0018 ml) at room temperature is
Answered by admin @
Density of water = 1 g/ml
mass of 0.0018 ml of water = 0.0018×1 = 0.0018 g
molar mass of water = 18 g/mol
number of moles in 0.0018g of water =
number of water molecules in 1 mole = 6.022×10²³ molecules
number of water molecules in
