Question

Calculate the mass of carbon dioxide and water when 1 mole of glucose burns in excess air. ​

Answer 1

Solution:

1 mole of carbon is burnt in air.

C+O

2

​

→CO

2

​

1 mole of C produces 1 mole of CO

2

​

 which corresponds to 44 g of CO

2

​

.

(ii) 1 mole of carbon is burnt in 16 g of dioxygen.

16  g of dioxygen corresponds to  

32

16

​

=0.5 moles.

Here, dioxygen is the limiting reagent.

It will produce 0.5 moles of CO

2

​

 which corresponds to 0.5×44=22 g of CO2
