Best answer: What is the mass of 1 mole of nitrogen atoms Class 9?

How many nitrogen atoms are there in 1 mole of nitrogen?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms. Also, one mole of nitrogen atoms contains 6.02214179×1023 nitrogen atoms.

What is the value of 1 mole Class 9?

Number of particles present in one mole of any substance is 6.022 X 1023. This value is called Avogadro number. So we get 1 mole = 6.022 X 1023 in number.

What is the mole of 1 mole of nitrogen atoms?

1 mole of nitrogen atoms is equivalent to the gram atomic mass of nitrogen. Therefore, 1 mole of nitrogen atoms contains 14 g.

What is the mass of 1 mole of an atom?

This can also be written as 6.022×1023 mol1. The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

What is the mass of 2 moles of nitrogen atoms?

Hence, 2 moles of nitrogen atoms weigh 28g.

What is the mass of 1 mole of oxygen?

Solution — Mass of one mole of oxygen molecule (O2) = molecular mass of oxygen molecule (O2) in gram = 32 g. Mass of a single oxygen molecule = 32/1 × 1024 = 3.2 × 10-23g.
