Question

How many atoms of hydrogen are in 0.56 mol of (NH4)2SO4

Express your answer using two significant figures.

Answer 1

Answer:
`2.7* 10^(24)` atoms

Step-by-step explanation:

The given formula of the compound is
`(NH_(4))_(2)SO{4}`

The formula says

Every mole of
`(NH_(4))_(2)SO{4}` contains
`8` moles of atoms of hydrogen.

Given that number of moles of compound is
`0.56`

So,the number of moles of hydrogen atoms present is
`0.56* 8=4.48`

Since each mole has
`6.022* 10^(23)` atoms,

`4.48` moles has
`4.48* 6.022* 10^(23)=2.7* 10^(24)` atoms.
