How to Calculate the Amount of Solute and Solvent in a Solution with 14% Mass/Mass Concentration?

What is the total weight of a solution that contains 127 grams and has a concentration of 14% mass/mass?

To calculate the amount of solute and solvent in a solution with a 14% mass/mass concentration, we need to determine the proportions of each component in the solution. In this case, the total weight of the solution is given as 127 grams, and the concentration is 14% m/m.

Calculating the Amount of Solute and Solvent:

First, we need to understand that the concentration of 14% m/m means that 14 grams of the solution is solute and 86 grams is solvent in every 100 grams of the solution.

Step 1: Calculate the amount of solute in the solution.

To find the amount of solute, we use the concentration percentage. Since the total weight of the solution is 127 grams, we multiply it by the concentration of solute (14%) in decimal form:

Solute = 127 grams * 0.14 = 17.78 grams

Step 2: Calculate the amount of solvent in the solution.

Since the total weight of the solution is 127 grams and we already know the amount of solute, we can find the amount of solvent by subtracting the amount of solute from the total weight:

Solvent = 127 grams - 17.78 grams = 109.22 grams

Therefore, in a 127-gram solution with a concentration of 14% m/m, there are approximately 17.78 grams of solute and 109.22 grams of solvent.
