Answer:
1) 25.44 moles H
2) 0.444 moles H
3) 792 moles H
Explanation:
Step 1: Number of moles H in 8.48 moles NH3
In 1 mol NH3 we have 3 moles H
For 8.48 moles NH3 we have 3*8.48 = 25.44 moles H
Step 2: Number of moles H in 0.111 moles N2H4
For 1 mol N2H4 we have 4 moles H
For 0.111 moles N2H4 we have 4*0.111 = 0.444 moles H
Step 3: Number of moles H in 36.0 moles C1OH22
For 1 mol C10H22 we have 22 moles of H
For 36.0 moles C1OH22 we have 22*36.0 = 792 moles H
