Question
How many moles of water are present in one litre of water?
- 55 L
- 55.5 L
- 55.5 moles
- All of the above
Hint:
Mass of 1 mole of water = 18g. Density of water = 1g/cc.
The correct answer is: 55.5 moles
Mass of 1 mole of water = 18g
Density of water = 1g/cc, volume of 1 mole of water is 18ml.
Number of moles in 1L of water = 1000
18 = 55.55 moles.
