Question

Which contains the greatest number of carbon atoms?A. 0.250 moles of glucose, C6H12O6B. 1.20 moles of carbon dioxide, CO2C. 0.450 moles of Al2(CO3)3D. 0.500 moles of CaC2E. 0.400 moles of C4HgO2S

Answer 1

To check The number of atoms in each alternative, we we can multiply the amount of carbon atom in each compound by the number of moles we have of it:

`\begin{gathered} A\colon0.250\cdot6=1.50 \\ B\colon1.20\cdot1=1.20 \\ C\colon0.450\cdot3=1.35 \\ D\colon0.500\cdot2=1.00 \\ E\colon0.400\cdot4=1.60 \end{gathered}`

Now, we can compare them. The one that has the greatest amount is alternative E.
