Final answer:
The concentration in terms of mass/volume percentage of a potassium chloride solution with 2.5 g of solute in 50 mL of solution is calculated as 5%.
Step-by-step explanation:
To calculate the mass/volume percentage of a solution containing 2.5 g of potassium chloride (KCl) in 50 mL of solution:
First, understand that mass/volume percentage is a way of expressing the concentration of a solution.
It is calculated by taking the mass of the solute, which in this case is potassium chloride, and dividing it by the volume of the solution, and then multiplying by 100 to get a percentage.
Here's the formula:
Mass/Volume Percentage (%) = (Mass of Solute (g) / Volume of Solution (mL)) × 100%
Using the formula:
Mass/Volume Percentage (%) = (2.5 g / 50 mL) × 100%
= 5%
The concentration in terms of mass/volume percentage of the potassium chloride solution is 5%.
