How many atoms of N (nitrogen) are there in 1 mole of NH4Cl?

In one mole of NH₄Cl  6.022 × 10²³ atoms of N are present.

Explanation:

Given data:

Number of atoms of N = ?

Number of moles of NH₄Cl = 1 mol

Solution:

First we have to calculate the number of  atoms in NH₄Cl .

There is only 1 mole of N in 1 mole of NH₄Cl .

Now we will calculate the number of atoms of nitrogen in one mole of N  by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1  mole of N = 6.022 × 10²³ atoms of N

Thus in one mole of NH₄Cl  6.022 × 10²³ atoms of N are present.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
