How many atoms of carbon are contained in 47.6 g of al2 (co3) 3? the molar mass of al2 (co3) 3 is 233.99 g/mol?

The molar mass of Al₂ (CO₃) ₃is 233.99 g/mol

It means 233.99 grams of Al ₂ (CO₃) ₃ are in one mole

And moles in 47.6 g = 47.6/233.99 = 0.203 moles

Now we know that we have 0.203 moles of Al₂ (CO₃) ₃

In one mole of Al₂ (CO₃) ₃, we have 3 moles of carbon

To find the number of moles of carbon in a 0.203 moles of Al₂ (CO₃) ₃, we must multiply this by the 3 moles of carbon

0.203 x 3 = 0.609 moles of carbon

Within one mole of carbon, we have 6.022 x 10 ²³ atoms. So, to find the amount of atoms within 0.609 moles of carbon, we must multiply the 0.609 moles by 6.022 x 10²³ atoms.

So, the number of carbon atoms present in 47.6g of Al ₂ (CO₃) ₃ = 0.609 x 6.022 x 10²³ = 3.667 x 10²³ atoms.
