WebWater has a molecular weight of 18. 42/18 is 2.33 repeating, so you have 2 1/3 moles of water. Since there are 6.02 X 10^23 molecules per mole, you would then have 1.04 X 10^24 molecules. 1,040,000,000,000,000,000,000,000 See, it’s that easy. It’s called math.

So one mole of water has a mass of 18 g. A liter is defined as the volume of 1 kg of water at standard temperature and pressure. 1 mL is thus the volume of 1 g, and 0.5 L is 500 mL or 500 g of water. Giver that 1 mole of water is 18 g, then 500 g of water must be 500 g / 18 g = 27.78 moles. birth squat bar
