How many atoms of hydrogen are in 0.56 mol of (NH4)2SO4
BabaBlast [244]
<h2>Answer:2.7\times 10^{24} atoms</h2>

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\times 8=4.48

Since each mole has 6.022\times 10^{23} atoms,

4.48 moles has 4.48\times 6.022\times 10^{23}=2.7\times 10^{24} atoms.
