Question

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

Answer 1

Should be 1

Step-by-step explanation:

Answer 2

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* 4* 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 * 10^23 H` atoms

So,

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

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

So, we get

=
`4.8176 * 10^22  \ H  \ atoms`

=
`4.82 * 10^22 \ H` atoms is the Answer.
