How many molecules of water are in a drop of water that weighs 5.0 mg?

molecules in a drop of water = 1.67 x 1021 water molecules.

How many water molecules are in a mL of water?

=3.34*10^25 molecules of water. Or 3.34*10^23 molecules in 1ml.

How many molecules of water are there in 1.000 L at STP?

3.343×1025 molecules.

How many water molecules are there in a water drop weighing 0.5 g?

0.05 g of H2O contain molecules =0.0518.0×6.022×1023=1.672×1021 molecules.

How many molecules are there in a drop of water weighing 45g?

=1.67 x 1^21 molecules.

How many molecules of water are there in 1 Litre of water the density of water is 1.0 gram per ml?

So, 1 liter =1000ml=1000g water contains 3.36*10^25 water molecule.

How many molecules are there in 1 Litre of any gas at STP?

Hence, the number of molecules in 1 liter of any gas at S.T.P is 0.27 × 1023 molecules.

How many molecules are present in 1000g of water?

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules.

How many molecules are there in one mole of water?

One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro’s number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)

How many molecules of H2O are there in 15 grams of water?

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol. So 1 g water will contain 1/18 moles of H2O molecules. Now 15 g of water will contain 15/18 moles of H2O.

How many molecules of water are there in 500 grams?

Giver that 1 mole of water is 18 g, then 500 g of water must be 500 g / 18 g = 27.78 moles. Given that there are 6.022 × 10 23 molecules per mole, then there must be 27.78 × 6.022 × 10 23 = 1.67 × 10 25 molecules of water per 500 mL. It’s been a long time since high school, but I think I got that right. What does Google know about me?

How many molecules of water are present in 18g of water?

18 g of water contains 1 mol of water molecules. or 18 g of water contains 6.022 x 10^23 water molecules. or 1 g of water contains (6.022 x 10^23)/ 18 water molecules and the number comes out to be 3.3455 x 10^22. So the number of water molecules present in 1 g of water is 3.3455 x 10^22. I hope you got the answer to your question.
