What is the approximate percentage concentration of 50 grams of solute in 2 liters of solution?

• A. 2.0%
• B. 2.5%
• C. 3.0%
• D. 1.5%

Answer: (B)

To determine the approximate percentage concentration of a solution, the formula used is: \[ \text{Percentage Concentration} = \left( \frac{\text{Mass of Solute (grams)}}{\text{Volume of Solution (milliliters)}} \right) \times 100 \] In this case, you have 50 grams of solute and 2 liters of solution. First, it's essential to convert liters to milliliters since the percentage calculations typically use milliliters for volume. 2 liters is equivalent to 2000 milliliters (as 1 liter = 1000 milliliters). Now we can plug the values into the formula: \[ \text{Percentage Concentration} = \left( \frac{50 \text{ grams}}{2000 \text{ mL}} \right) \times 100 \] Calculating this gives: \[ \text{Percentage Concentration} = \left( \frac{50}{2000} \right) \times 100 = 0.025 \times 100 = 2.5\% \] Therefore, the approximate percentage concentration of the solution is 2.5%. This value matches the
