One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

Answer Expert Verified This indicates Sulfur has 2 atoms. Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms.

There are 6 of these molecules. H2O is a molecule made of H for hydrogen and O for oxygen. There are 12 of these molecules. The smaller number is the number of atoms of the element to the left of it.

For example, since one atom of oxygen will combine with two atoms of hydrogen to create one molecule of water (H2O), one mole of oxygen (6.022×1023 of O atoms) will combine with two moles of hydrogen (2 × 6.022×1023 of H atoms) to make one mole of H2O.

So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule . Now, 1 molecule of oxygen contains 2 atoms. Hence, 2mole of O2 contains 2 ×2 ×6.023 ×10^23 atoms = 24.

A single mole of O2 has 6.02 * 10^23 oxygen molecules. Each oxygen has 2 atoms of oxygen. Therefore, 2(6.02 * 10^23) = 1.2 * 10^24.

There are 24 atoms in one molecule of C6 H12 06. This chemical compound has 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.

Answer. Explanation: In the given formula, there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.

The molecular formula of a compound tells us how many atoms of each element are in one molecule. A carbon dioxide molecule, which has the formula CO2, contains one carbon atom and two oxygen atoms.

Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element. Fig.

Well, one mole is equal to Avogadro's Number, or 6.02210 x 10^23 particles. Since you are not talking about the amount of oxygen atoms in 3 moles of O2, no extra multiplication is needed to compensate for that. 3 moles x (6.02210 x 10^23) O2 molecules per mole = 1.80663 x 10^24 O2 molecules.

For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3.

Likewise, a molecule of oxygen gas has the formula O2 . The molar mass of a single oxygen atom is 16 g/mol. The molar mass of an O2 molecule is 2 x 16g/mol = 32 g/mol.

How many atoms of oxygen and hydrogen are present in 0.15 mole of water ? No. of oxygen atoms present =0.15×6.022×1023=9.03×1022 atoms.
1245607
These are different things. A mole of oxygen molecules contains 2 moles of oxygen atoms.
24523
Answer and Explanation: A mole of CO2 contains 12.044 X 1023 oxygen atoms.

There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms.
