The number of molecules present in 1 cmcube of water is:-

Answer 1

Calculate the number of molecules present in one lLof water assuming the density of water of water is 1g/cm3. 1 liter of water is equal to 1000 mL or 1000 g (1 mL = 1 g). Multiplying this number by 6.022 × 1023 or Avogadro's number (1 mole = 6.022 × 1023 particles) will yield about 3.345 × 1025
