Given the general chemical equation 3A + 2B → C + 5D,

a. How many moles of D can be produced from 4 moles of A?

b. How many liters of D can be prepared from 9.8 L of B?

Answer :

(a) The number of moles of D produced can be, 6.67 moles.

(b) The volume of D prepared can be, 24.5 L

Explanation :

The given chemical reaction is:

Part (a) :

From the balanced chemical reaction, we conclude that:

As, 3 moles of A react to give 5 moles of D

So, 4 moles of A react to give moles of D

Thus, the number of moles of D produced can be, 6.67 moles.

Part (b) :

As we know that 1 moles of substance occupies 22.4 L volume of gas.

As, volume of B gives volume of D

As, 9.8 L volume of B gives volume of D

Thus, the volume of D prepared can be, 24.5 L

the right answer is c i just did the question.
