First, NaCl is very soluble in water. There are two moles of ions (one sodium and one chloride) on the product side. A mole is Avagadro's number. 2 moles x 6.02 x 10^23 ions/mole = 1.2 x 10^24 ions.

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.

Two water molecules will sometimes combine into hydronium and hydroxide ions. Pure water is considered to neutral and the hydronium ion concentration is 1.0 x 10-7 mol/L which is equal to the hydroxide ion concentration.

Answer and Explanation: There are 1.5 moles of water in a 27 gram sample of water.

1 mole of water weighs equal to the molecular mass of water. Thus the amount of present in 0.25 mole of it​ is 4.5 grams.

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.

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.

Number of molecules, hydrogen atoms and oxygen atoms present in 0.5 mole of water. 0.5 mol of water = molecules. Water is composed of 2 hydrogen atoms and one oxygen atom. 0.5 mol of water = 6.022× atoms of hydrogen.

So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.

1 mole of CaCl2 consists of 1 mole Ca2+ and 2 mole Cl–. If 1 mole of Cl– is 6.02 x 1023 Cl– ions, then 1 mole of CaCl2 contains (2 x 6.02 x 1023) Cl– ions or 1.20 x 1024 Cl– ions.

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.

Dissolved in the water are trace amounts of minerals, lactic acid, and urea. Although the mineral content varies, some measured concentrations are: sodium (0.9 gram/liter), potassium (0.2 g/L), calcium (0.015 g/L), and magnesium (0.0013 g/L).

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.

“The product of concentrations of and ions in water at a particular temperature is known as ionic product of water.” It is designated as . The value of increases with the increase of temperature, i.e., the concentration H+ and OH– ions increases with increase in temperature. The value of at is mole/litre.

Ionic compounds are soluble in water due to dipole dipole force. All ionic compounds would be dissolved in water because ionic compounds are made up of ions, and that ions would be attracted by the negative and positive poles of water, so ionic crystals would be dissolved in wster.

Compounds and the Mole So, one mole of NaCl weighs 58.5g. Let's think about this a bit further: 58.5g of NaCl will contain one mole of sodium ions and one mole of chloride ions. So, 58.5g of NaCl contains two moles of ions in total.

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. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.
