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.

1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom!

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.

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.

1 mole of oxygen reacts with 2 moles of carbon to produce 2 moles of CO. Now 0.245g of CO = 0.245/28 = 0.0088 mole and this will require 0.0088/2 = 0.0044 mole of oxygen. Every mole of oxygen contains 6.022 x 10^23 molecules of oxygen.

There are 6.022×1023 O2 molecules in a mole of O2. Since you have 2 oxygen atoms in one O2 molecule, there are 2×6.022×1023 O atoms in a mole of O2.
327105
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. 092 ×10^23 atoms.

In one mole of atomic oxygen, O, there are 6.022 x 10^23 atoms O. In one molecule of O2, the form of oxygen that we breathe, there are two oxygen atoms.

1 g contains → 6.022 × 1023 / 32 molecules of di oxygen. ⇒ 1 g contains → 0.188 × 1023 molecules of di oxygen. ∴ 8 g contains → 0.188 × 8 × 1023 molecules of di oxygen. =1.505 * 1023 molecules.

moles = 360 × 10-³ ÷180 = 2 × 10-³ mole. number of molecules in one mole = 6.023 × 10^23 ( Na) therefore, number of molecules in 2 × 10^-3 × Na. 1 molecule of aspirin contains 4 atoms of oxygen.

32 g of oxygen is two moles of oxygen atoms. That's approximately 2 x 6 ^23 oxygen atoms.

We assume you are converting between moles Oxygen and gram. You can view more details on each measurement unit: molecular weight of Oxygen or grams The molecular formula for Oxygen is O. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Oxygen, or 15.9994 grams.

per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

A million CO2 molecules have one million carbon atoms and two million oxygen atoms. A mole of CO2 molecules (we usually just say “a mole of CO2”) has one mole of carbon atoms and two moles of oxygen atoms.
