Answer: The number of hydrogen atoms in a given chemical formula are [tex]7.2264\times 10^{24}[/tex]
Explanation:
We are given a chemical compound having chemical formula of [tex]NH_3[/tex]
In 1 mole of ammonia, 1 mole of nitrogen atom and 4 moles of hydrogen atoms are there.
According to mole concept:
1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of atoms.
So, 3 moles of ammonia will contain = [tex]3\times 4\times 6.022\times 10^{23}=7.2264\times 10^{24}[/tex] number of Hydrogen atoms and [tex]3\times 1\times 6.022\times 10^{23}=1.8066\times 10^{24}[/tex] number of nitrogen atoms.
Hence, the number of hydrogen atoms in a given chemical formula are [tex]7.2264\times 10^{24}[/tex]
