Question

What is the number of molecules of carbon dioxide in 22g?

Answer 1

As one mole of carbon dioxide contains 6.02×1023 atoms of carbon, half mole of carbon dioxide will contain half of the 6.02×1023 atoms of carbon and that will be equal to 3.01×1023 carbon atoms. Therefore, 22 g of carbon dioxide will contain 3.01×1023 carbon atoms, which is option B.
