Answer:
See below 
Step-by-step explanation:
H2 S shows that each mole of H2S has two moles of H in it 
 so 10 moles of H2S would have 20 moles of H 
Each mole is Avagadro's Number of atoms 
 20 moles * 6.022 x10^23 atoms/mole = 120.44 x 10^23 toms of H
H2S has one mole of S for each mole of H2S 
 there are then 10 moles of S
 10 * 6.022 x 10^23 = 60.22 x 10^23 atoms of S
