Determine the number of moles of C in each sample 2.0 mol CH4, 0.175 mol C2H6,
4.21 mol C4H10, 24.5 mol C8 H18

Explanation:

Given moles = 2.0 moles

1 mole of methane contains 1 mole of carbon and 4 moles of hydrogen

Moles of carbon in

Given moles = 0.175 moles

1 mole of ethane contains 2 moles of carbon and 6 moles of hydrogen

Moles of carbon in

Given moles = 4.21 moles

1 mole of butane contains 4 moles of carbon and 10 moles of hydrogen

Moles of carbon in

Given moles = 24.5 moles

1 mole of octane contains 8 moles of carbon and 18 moles of hydrogen

Moles of carbon in

the answer is alpha particles hope i you

a polar bond is formed when electrons are shared unevenly between atoms
