Answer 2

Given: $0.80$ moles of $C_{6} H_{14}$.

To find: number of hydrogen atoms.

Step-by-step method:

Step 1 of 2

1 mole of hexane has $6.022*10^{23}$ molecules of hexane.

0.8 mole of hexane will have $0.8*6.022*10^{23}$ molecules of hexane. That is $4.8176*10^{23}$ molecules of hexane.

Step 2 of 2

1 molecule of hexane has 14 atoms of hydrogen.

$4.8176*10^{23}$ molecules of hexane will have  $14*4.8176*10^{23}$  atoms of hydrogen. That is $67.4464*10^{23}$ atoms of hydrogen.

There are $67.4464*10^{23}$ atoms of hydrogen in hexane.
