How many moles of carbon are in 3.5 moles of calcium carbonate?

Answer : The number of moles of calcium carbonate are 3.5 moles.

Explanation : Given,

Moles of carbon = 3.5 mole

The chemical formula of calcium carbonate is,

By the mole concept:

In , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.

As, 1 mole of carbon present in 1 moles of

So, 3.5 mole of carbon present in 3.5 moles of

Hence, the number of moles of calcium carbonate are 3.5 moles.
