how many moles of water can you make?
435473
For example, when oxygen and hydrogen react to produce water, one mole of oxygen reacts with two moles of hydrogen to produce two moles of water. In addition, stoichiometry can be used to find quantities such as the amount of products that can be produced with a given amount of reactants and percent yield.

The density of water is 1 gram per cc, so 1 mole of water takes 18cc of volume. 1 cup is approximately 250ml (i.e. 250cc) - so 1 cup will contain approximately 13.89 moles of water, which will contain approximately 8.36 x 1024 molecules of water.

Divide the mass of water by the molar mass of water to get moles of water. 2.60 g H2 O / (18.00 g/mol H2 O) = 0.144 moles H2 O. Divide the mass of anhydrate by the molar mass of anhydrate to get moles of anhydrate.

Thus, for example, one mole of water contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams – and the mean mass of one molecule of water is about 18.015 daltons.

Notice that the reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.

Mass of 1 Mole of Water How much water is that to most people? 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.

Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water.

6 mole of octane produces 54 moles of water. 2. 8 moles of carbon dioxide can be produced from 12.5 moles of oxygen.
51226
one mole of water contains 6.02 x 1023 MOLECULES of water.

6. How many moles of water can be produced from the reaction of 45 g of O2? 45 g O2 X 1 mole O2 X 4 moles H2O = 1.125 moles H2O 32 g O2 5 moles O2 8.

Example: If someone can fit 200 gram (ml) of water into their mouth, how many moles of water is this: 200 grams of water x 1 mole of H2O = 11 moles 18grams 4. To find how many molecules of water are in someone's mouth: A mole of anything has 6.02x 1023 particles (this is Avogadro's number).

So we need to find the moles of water in 1 L of water or 1000mL of water. Taking the density of water to be 1g/mL, 1000mL of water= 1000g water. =3.34*10^25 molecules of water. Or 3.34*10^23 molecules in 1ml.

Density of Water One drop of water is 0.05 mL of water, so its mass would be 0.05 grams. One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles.

Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules.

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. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*1026 atoms in a liter of water.

Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen ! There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole.
