Question

Calculate the number of atoms in 4 mole atoms of nitrogen

Answer 1

Explanation:

According to Avogadro, there are $6.023 \times 10^{23}$ atoms or molecules present in 1 mol.

Since, molar mass of nitrogen atom is 14. Therefore, in 4 mole atoms of nitrogen calculate the number of atoms as follows.

                     = $4 mol \times 6.023 \times 10^{23} atoms/mol$

                     = $24.092 \times 10^{23}$ atoms

Thus, we can conclude that there are $24.092 \times 10^{23}$ atoms in 4 mole atoms of nitrogen.                  

Answer 2

Answer:

24.088× 10∧23

Explanation:

see guys here it is asked about how many atom is present in 4 moles of nitrogen atom .

as we know 1 mole = 6.022 × 10∧23 atoms . it can be of any element no maters .

∴ now for 4 mole of nitrogen = 4 × 6.022×10∧23 =   24.088  × 10∧23

now by folowing significant figure law we can write 2.4088 × 10∧24
