Question: What is equivalent to a mole of oxygen atoms?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms. Also, one mole of nitrogen atoms contains 6.02214179×1023 nitrogen atoms. The number 6.02214179×1023 is called Avogadro’s number (NA) or Avogadro’s constant, after the 19th century scientist Amedeo Avogadro.

How do you calculate moles of oxygen?

  1. Given mass = 320 g.
  2. The moles of oxygen molecules = Given mass / Molar mass.
  3. = 320 g / 32 g.
  4. = 10.

What is a mole equivalent to?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.
