What is the mole ratio of d to a in the generic chemical reaction? 4a + b --> c + d

Mole ratio of D to A is 1 : 4

Explanation:

We are given the generic chemical equation;

4A + B → C + D

We are supposed to determine the mole ratio of D to A

What is mole ratio?

Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.We determine the mole ratio using the coefficients of reactants or products in question.

For example;

In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of DThus, mole ratio of D to A  is 1 : 4

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"
