Answer:
Weight/Volume Percentage = (Mass of Solute / Mass of Solution) * 100
= (16 g / 120 g) * 100
= 13.3%
Explanation:
The concentration of a solution can be expressed in various units such as molarity, molality, or weight/volume percentage. In this case, we can express the concentration of the solution as weight/volume percentage.
Weight/volume percentage is a measure of the concentration of a solute in a solution, expressed as the weight of the solute in grams, per 100 mL of solution. To calculate the weight/volume percentage of the solution, divide the mass of the solute (urea) by the mass of the solution (120 g) and multiply by 100.
Weight/Volume Percentage = (Mass of Solute / Mass of Solution) * 100
= (16 g / 120 g) * 100
= 13.3%
So, the solution that contains 16g of urea in 120g of solution has a weight/volume percentage of 13.3%. This means that 13.3% of the solution by weight is composed of urea, and the remaining 86.7% is composed of the solvent (the component in which the solute is dissolved).
