Contents

## 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.
