From the formula of the compound, we can see that there are 10 moles of hydrogen present in every mole of the compound. In the given amount:

Moles of hydrogen = 10 * 0.75
Moles of hydrogen = 7.5

Next, we know that each mole of a substance contains 6.02 x 10²³ particles. The atoms of hydrogen will be:
7.5 * 6.02 x 10²³ 

4.515 x 10²⁴ atoms of hydrogen will be present.
