Explain to the class that the beaker contains 342.3 g (1 mole) of sucrose. This quantity of sucrose contains 6.02 × 1023 (Avogadro's number) of sucrose molecules.
940970
So 1kg contains 1000/342.3 = 2.921mol sucrose. 45 x 2.921 x 6.022x10^23 = 7.916x10^25 atoms in 1kg of sugar.

Since there are 6 moles of carbon in 1 mole of glucose then the number of moles of carbon is equal to 0.10 moles of glucose times 6 moles of carbon. The simplified answer is 0.60 moles of carbon in 18 g of glucose.

The number of particles is present in One mole equals to Avogadro number. So, the number of glucose molecules in one mole is 6.022 * 10^23.

What is sugar? The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.

As one mole of H2 contains 6.022×10^23 molecules of H2. And one molecule contain 2 Hydrogen atoms. So, 1 mole of H2 will have 1.2044×10^24 atoms.

In order to work this out, multiply Avogadro's number - the one I stated at the start of this explanation - by 2 . This will give you the number of molecules in 2 moles of a substance. In other words, 1 mole of atoms is 6.02×1023 atoms. 1 mole of molecules is 6.02×1023 molecules.

A carbon dioxide molecule, which has the formula CO2, contains one carbon atom and two oxygen atoms. This information is contained in the subscripts after each element. A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.

A mole of a molecular compound contains 6 x 10 23 molecules. It has a mass that is equal to its relative formula mass . So a mole of water (H 2O) has a mass of 18 g. A mole of carbon dioxide (CO 2) has a mass of 44 g.

According to Avagadro, there are 6.022 × 10^23 molecules in 1 mole of any compound, irrespective of elements or the mass of compound. Thus in 3 moles of O2, there are 3 ×6.022× 10^23 molecules of O2, that is, 18.066×10^23 molecules of O2.

There are 6,022*10^23 molecules in a mole, and there are 3 phospates in one ATP molecule and 2 of them may be splitted off. 2 * 6,64 * 10^(-20) = 1,33 * 10^(-19) joules.

divide 345 grams by molar mass which is 44 . 01 grams per mole to give the number of moles. 1 mole contains 6.022 x 10^23 molecules.

One molecule of glucose has 6 atoms, as you can see in carbon's index. ( C6 ). In 20 molecules there will be 6⋅20 carbon atoms. So, written down like this there are 20⋅6 carbon molecules, 12⋅20 hydrogen atoms and 6⋅20 oxygen molecules.

And since one mole represents 6.022×1023 individual molecules.....we take the quotient......

A pound-mole is comprised of 6.022 141 79 × 1023 453.59237 molecules, i.e. the pound-mole is that amount of substance that contains the same number of elementary entities as there are atoms in 453.59237 grams of carbon 12.
