For a mixture with liquids A and B with different concentrations, what is the formula for determining the final ratio of liquids?

Sum of elements divided by the required concentration
Difference of each concentration from the desired concentration
Average of the two liquid concentrations
Product of both concentrations

The correct answer is: Difference of each concentration from the desired concentration

To determine the final ratio of two liquids A and B with different concentrations, the relevant approach involves comparing each liquid's concentration to the desired concentration of the final mixture. The formula reflects the difference each concentration has from the required concentration, which helps in establishing how much of each liquid is necessary to achieve the target concentration. This method is based on the concept of balancing the contributions of each liquid to meet the desired overall concentration. By calculating the difference of each concentration from the desired concentration, you can effectively determine the necessary proportions of liquids A and B that will yield the final mixture with the intended properties. This approach ensures that the resulting mixture has the correct concentration, leveraging the specific contributions of each original liquid while allowing you to adjust for the strengths of each component. It creates a basis for setting up the ratio correctly.
