The Number of Water Molecules is Maximum in (A) 18 moles of water (B) 18 grams of water (C) 1.8 grams of water (D) 18 molecules of water

Answer: (A)

Explanation: 

  • If one mole of water is equal to 6.02×1023 molecules,

Then 18 moles of water are equal to 18×6.02×1023 molecules.

As a result, the maximum number of molecules in 18 moles of water.

  • 18 grams of water is equal to 0.9992 moles
  • 108 grams of water is equal to 0.09992 moles
  • 18 molecules of water is equal to 2.9889699536286003e-23.
