Question

In the reaction of Epsom Salt and ammonia, how many atoms of Hydrogen are in the product, ammonium sulfate (NH4)2SO4

Answer 1

Answer:

Epsom salt is Magnesium sulphate $(MgSO_4)$

So the chemical reaction is  

$MgSO_4+2 NH_3+2H_2 O > 1(NH_4 )_2 SO_4+Mg(OH)_2$  

$1(NH_4 )_2 SO_4$  contains $1\times 4\times 2=8$ 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 $6.022 \times 10^23 H$ atoms

So,  

$8 \ mole \ H \ atoms \times \frac {(6.022 \times 10^23 \ H \ atoms)}{(1 \ mole \ H \ atoms)} = 48.176 \times 10^23 \ H \ atoms$

Moving the decimal point to the right, the power of 10 decreases

So, we get  

=  $4.8176 \times 10^22 \ H \ atoms$

= $4.82 \times 10^22 \ H$ atoms is the Answer.
