Chemistry The **Mole** Concept The **Mole** 1 Answer Doc048 Jun 23, 2017 6.02 ×1023 **Oxygen** **atoms** Explanation: **One** **mole** **of** any substance **contains** **one** Avogadro's Number of particles. Avogadro's Number = 6.02 ×1023 particle units Answer link. Answer (1 of 7): The trick is the question "**How** **many** **atoms** **of** H per **Mole** **of** **water**" take Avogrado's # for a **Mole** **of** **water**, and divide by 2/3 (2 H's and 1 O). Should end up with the same number of **atoms** as 2 **Moles** **of** H using the traditional method since the number of **atoms** is invariable. **One** **mole** **of** **water** **contains** Avogadro's number of molecules i.e 6.023 * 10^23 **water** molecules. Since **water** is H2O , **one** molecule has 3 **atoms** (2 of hydrogen,1 of oxygen).So total **atoms** = 3*6.023*10^23 = 18.069*10^23 **atoms**. number of **moles** = 18 g 1.008 g/mol × 2 + 16.00 g/mol = 18 g 18.02 g/mol ≈ 1 **mole**. In 1 **mole** **of** **water**, there are 6.022 × 1023 molecules—that's **how** the **mole** was defined! And, since the chemical formula for **water** is H 2O, 1 **mole** **of** **water** corresponds to 1 **mole** **of** **oxygen** **atoms**. Therefore, there will be 6.022 × 1023 **oxygen** **atoms** in 1 **mole**, or.

Just as 1 **mole** **of** **atoms** **contains** 6.022 × 10 23 **atoms**, 1 **mole** **of** eggs **contains** 6.022 × 10 23 eggs. This number is called Avogadro's number, after the 19th-century Italian scientist who first proposed a relationship between the volumes of gases and the numbers of particles they **contain**.

Assume all the **oxygen** in the **water** is normal **oxygen**-16. So, **one** molecule of heavy **water** will have 10 neutrons (**one** in each of the two deuterium **atoms** and 8 in the **oxygen** **atom**. A **mole** **of** anything **contains** 6.02E23 items. So a **mole** **of** heavy **water** will have 60.02E23 (6.02E24) neutrons. Which **one** **contains** more **oxygen** **atoms**? 22 grams of carbon dioxide or 18 grams of **water**?. **How many atoms of oxygen** are there in 18 g **of water**? – As in **one mole of water** there are6.022×1023 molecules that’s how the **mole** was defined. And as the chemical formula for **water** is H2O and **one mole of water** corresponds to **one mole of oxygen atoms**. Hence there will be 6.022×1023 **oxygen atoms** in **one mole** or we can say 18 g **of water**. Hence we can say that there are three **oxygen** **atoms** and **one** sulphur **atom** in this compound. Therefore, the correct answer is that **one** **mole** **of** sulphur trioxide **contains** 18.066 × 10 23 molecules of **oxygen** or in other words this chemical has 18.066 × 10 23 **atoms** **of** **oxygen**. Note that this chemical compound that is sulphur trioxide is a significant. One mole of water contains Avogadro’s number of molecules i.e 6.023 * 10^23 water molecules. Since water is H2O , one molecule has** 3** atoms (2 of hydrogen,1 of oxygen).So total atoms = 3*6.023*10^23 = 18.069*10^23 atoms.
