Explanation:
Given moles = 2.0 moles
1 mole of methane contains 1 mole of carbon and 4 moles of hydrogen
Moles of carbon in [tex]CH_4=(2.0\times 1)=2.0 moles[/tex]
Given moles = 0.175 moles
1 mole of ethane contains 2 moles of carbon and 6 moles of hydrogen
Moles of carbon in [tex]C_2H_6=(0.175\times 2)=0.35 moles[/tex]
Given moles = 4.21 moles
1 mole of butane contains 4 moles of carbon and 10 moles of hydrogen
Moles of carbon in [tex]C_4H_{10}=(4.21\times 4)=16.84 moles[/tex]
Given moles = 24.5 moles
1 mole of octane contains 8 moles of carbon and 18 moles of hydrogen
Moles of carbon in [tex]C_8H_{18}=(24.5\times 8)=196 moles[/tex]
