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, [tex]CaCO_3[/tex]
By the mole concept:
In [tex]CaCO_3[/tex], 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 [tex]CaCO_3[/tex]
So, 3.5 mole of carbon present in 3.5 moles of [tex]CaCO_3[/tex]
Hence, the number of moles of calcium carbonate are 3.5 moles.
The number of moles of Carbon contained in 3.5 moles of Calcium Carbonate is; 3.5 moles of Carbon.
According to the question;
We are required to determine How many moles of carbon are in 3.5 moles of calcium carbonate.
The chemical formula of Calcium Carbonate is; CaCO3.
In essence, Calcium Carbonate contains;
Consequently, since 1 mole of Calcium Carbonate contains 1 mole of Carbon.
By proportion, 3.5 moles of Calcium Carbonate must contain 3.5 moles of Carbon.
