Question

What is the mole ratio of D to A in the generic chemical reaction? 2A+B >C+3D

Answer 1

Answer:  D : A is 3 : 2.

Explanation:

The law of definite proportion is being used here. The law states that a given compound always has the same proportion of its constituent elements by mass. The numbers written in the equation are used to balance it, which is an important part whilst determining the mole ratio

Keeping in mind law:

2a + b => c + 3d

Using the concept of stoichiometry coefficients of d and a  

So the ratio of d:a is 3:2

Answer 2

Answer: The mole ratio of D : A is 3 : 2.

Explanation: Mole ratio for a chemical reaction is the ratio of their respective stoichiometric numbers or the ratio of their moles in a chemical reaction.

For a given chemical reaction:

$2A+B\rightarrow C+3D$

By stoichiometry,

2 moles of A is reacting with 1 mole of B to produce 1 mole of C and 3 moles of D.

So, Mole ratio of D is to A will be 3 : 2
