Question: What is the mole of 18gm of water molecule?

What is the mole of one molecule of water?

A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. Therefore, one mole of water weighs 18.0152 grams.

How do you find moles of water molecules?

Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. From the periodic table we see the atomic weight of hydrogen is 1.0079 and the atomic weight of oxygen is 15.9994.

How many moles are in 18ml of water?

Thus, the mass of the water is 18g. This is the same as the molecular mass of water. Now we can calculate the moles of water present using the below formula. So, the number of moles of water will be [dfrac{{18}}{{18}} = 1] mole.

How many grams is 5 moles of water?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

What is 1 mole of a molecule?

One mole of anything is 6.022×1023 objects of anything. You may recognize 6.022×1023 as Avogadro’s number. One mole of molecules is 6.022×1023 molecules.

What is the mass of 2 mole of water?

One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

How many moles of molecules are there in 180g of H2O?

Moles of water =18018=10 mole.

What is the mole of H2O?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

How many molecules of H2O are there in 4.0 mol of H2O?

If you have 6.022⋅1023 molecules of water, then you can say for a fact that you have 1 mole of water. Now, you know that your sample contains 4.0 moles of water. In order to find the number of molecules of water it contains, you can use Avogadro’s constant as a conversion factor.
