Question

How many moles of carbon are in 6.0 moles of quinine

Answer 1

The molecular formula of quinine is C20H24N2O2. For every 1 mole of quinine molecule, there are 20 moles of carbon. Simply multiplying 6.0 moles by 20, we get, 120 moles.
Therefore, there are 120 moles of carbon in 6.0 moles of quinine.
