Answer:
Epsom salt is Magnesium sulphate [tex](MgSO_4)[/tex]
So the chemical reaction is
[tex]MgSO_4+2 NH_3+2H_2 O > 1(NH_4 )_2 SO_4+Mg(OH)_2[/tex]
[tex]1(NH_4 )_2 SO_4[/tex] contains [tex]1\times 4\times 2=8[/tex] mole of H atoms
That is to find the number of atoms we multiply coefficient subscript number outside the Bracket
1 mole of H atoms contains [tex]6.022 \times 10^23 H[/tex] atoms
So,
[tex]8 \ mole \ H \ atoms \times \frac {(6.022 \times 10^23 \ H \ atoms)}{(1 \ mole \ H \ atoms)} = 48.176 \times 10^23 \ H \ atoms[/tex]
Moving the decimal point to the right, the power of 10 decreases
So, we get
= [tex]4.8176 \times 10^22 \ H \ atoms[/tex]
= [tex]4.82 \times 10^22 \ H[/tex] atoms is the Answer.
