In the formation of a compound, carbon and oxygen react in the ratio 3

1.	In the formation of a compound, carbon and oxygen react in the ratio 3 : 8 by mass to form carbon dioxide. What mass of oxygen is required to react completely with 9 g of carbon?
Answer» For 3 g of carbon, 8 g of oxygen is needed. For 1 g of carbon, \(\frac { 8 }{ 3 }\) g of oxygen is needed. For 9 g of Carbon, \(\frac { 8 }{ 3 }\) g × 9 g = 24 g of oxygen is needed.
