how many molecules of water in a drop?
197276
molecules in a water drop = (6.022 x 102^3 molecules/mole) x 0.002275 moles. molecules in a water drop = 1.67 x 10^21 molecules of water.

( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms. If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water.

3.50⋅mol×6.022×1023⋅mol−1≅21×1023 individual water molecules.

The question is asking for “how many hydrogen atoms are present” though and currently, we have the number of water molecules in 2.84 mol. So, all we need to do is multiply that value by two as there are 2 Hydrogen atoms for every 1 water molecule.

In another way; there are 1.67 sextillion water molecules in a water droplet. Now, the number of atoms in one drop of water is 3x the number of molecules: atoms in a drop of water = 3 atoms/molecule x 1.67 x 1021 molecules. atoms in a drop of water = 5.01 x 1021 atoms.

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.

molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles. molecules in a drop of water = 1.67 x 1021 water molecules.

Answer and Explanation: The number of molecules of water in one mole of H2 O is 6.022140857 X 1023. This is because one mole contains 6.022140857 X 1023 particles or basic...

1 mol of water contains 6.022 × 1023 H2O molecules Therefore 0.500 mol contains 0.500 × (6.022 × 1023) = 3.01 × 1023 H2O molecules.

9 grams of water is 1/2 mole which is… 3.012 x 10^23 molecules.

If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x 6.022 x 10^23 molecules of water.

There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.

That means, per droplet, you have to divide that number by 24,000 because there are 24,000 droplets in a litre. So there must be 1.39 X 1021 molecules of water in an individual droplet of water, which is an amazing number of molecules. The volume of the Earth's oceans is 1.37 X 109 cubic km.

Avogadro's number tells us that there are 6.022 x 10^23 molecules of water per mole of water. So, next, we calculate how many molecules there are in a drop of water, which we determined: molecules in a water drop = (6.022 x 102^3 molecules/mole) x 0.002275 moles.

0.05 grams of water contains= 6.02*10^23*0.05/18= 1.67*10^21 molecules. (ans.) 2. 1 molecule of water contains= 2 atoms of hydrogen.

When you say ice, I'm assuming you mean . Now (2*1 + 1*16 = 18) g of water ice has molecules of . Each molecule of water has 2 hydrogen atoms so that's atoms of hydrogen.
