Q. 9.37 - An Introduction to General, Organic, and Biological Chemistry

Question

What is the difference between a $5.00\% (m/m)$ glucose solution and a $5.00\% (m/v)$ glucose solution?

Step-by-Step Solution

Answer

$5\% (m/m)$ is mass percent concentration and that defines the mass of solute. It indicates $5 g$ of glucose in $100 g$ of solution.

$5\% (m/v)$ is the mass/volume percent that is calculated by dividing grams of solute with volume of solution. It represents $5 g$ of glucose in $100 mL$ of solution.

Step 1: Given Information.

The following are the given information:

$5.00\% (m/m)$

$5.00\% (m/v)$

To find the difference between both the glucose solution.

Step : Explanation.

The mass percent concentration is $5\% (m/m)$, which describes the mass of a solute in every $100 g$ of solution. As a result, it denotes $5 g$ of glucose per $100 g$ of solution. The mass/volume percent $5\% (m/v)$ is calculated by dividing the grammes of the solute even by volume of solution and doubling by $100$.

It denotes the number of grammes of a wide range of compounds in $100 mL$ of a solution. So $5 g$ of glucose is present in $100 mL$ of solution.
