Determine the number of moles of H in each sample.

1). 8.48 mole NH3

2).0.111 mole N2H4

3). 36.0 mole C10 H22

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

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the temperature of the gas, in k, not celsius.
