How many moles of carbon are in 5.2 moles of c7h18?

Answer : The number of moles of carbon are, 36.4 moles.

Explanation : Given,

Moles of = 5.2 mole

First we have to determine number of carbon and hydrogen atoms present in .

As we know that, in there are 7 atoms of carbon and 18 atoms of hydrogen.

Now we have to determine the moles of carbon.

As, 1 mole of contains 7 moles of carbon.

So, 5.2 moles of contains moles of carbon.

Hence, the number of moles of carbon are, 36.4 moles.
