Question

In an experiment, the following reaction takes place.
C(s)+O2(g)CO2(g)12 g    32 g         44 g
How much mass of carbon dioxide will be produced, when 12
 g of carbon reacts with 48 g of oxygen?
  1. 14 g

  2. 10 g

  3. 8 g

  4. 7 g


Solution

The correct option is C

8 g


  • Elements always combine together in a constant ratio by mass to form a compound.
  • 12 g of carbon reacts with 32 g of oxygen, so the mass ratio is 12:32 or 3:8. 
  • This means that carbon will always combine with oxygen in 3:8 by mass to form carbon dioxide.
  • Hence, 12 g of carbon will combine with 32 g oxygen and produce 44 g of carbon dioxide.
  • Therefore, in the given situation, 48-32 = 16 g of oxygen will be left unreacted.
