Question

If 1 gram hydrogen has 1 mole atoms, how many atoms will be there in 7 grams of nitrogen.​

Answer 1

Explanation:

The result is 2.54 x 10^23 atoms. So, in 14 u, there will be 6.022 x 10 23 / 2 atoms. Therefore 7 gms of nitrogen is 7/28 gm-mole or 0.25 gm-mole As per Avogardo's Law number of atoms in 1 mole of any substance = 6 x 10 to the power -23.
