How many mol of carbon in 2.0 mol of caffeine?

Answer : The number of moles of carbon in 2.0 mole of caffeine are, 16 moles

Solution :

The formula of caffeine is,

As we know that, 1 mole of caffeine contains 8 moles of carbon atom, 10 moles of hydrogen atoms, 4 moles of nitrogen atoms and 2 moles of oxygen atoms.

According to the question,

As, 1 mole of caffeine contains 8 moles of carbon atoms

So, 2 moles of caffeine contains moles of carbon atoms

Therefore, the number of moles of carbon in 2.0 mole of caffeine are, 16 moles

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
