Calculating Mass by Volume Percentage Concentration
This question requires calculating the concentration of a solution in terms of mass by volume percentage. We are given the mass of the solute and the total volume of the solution.
Given Information
- Mass of solute = 5 g
- Volume of solution = 250 mL
Formula for Mass by Volume Percentage
The mass by volume percentage concentration is calculated using the following formula:
\( \text{Concentration (mass by volume } \%) = \frac{\text{Mass of solute (g)}}{\text{Volume of solution (mL)}} \times 100 \)
Step-by-Step Calculation
- Substitute the values: Plug the given mass of solute and volume of solution into the formula.
\( \text{Concentration} = \frac{5 \text{ g}}{250 \text{ mL}} \times 100 \)
- Simplify the fraction: Divide the mass of solute by the volume of the solution.
\( \frac{5}{250} = \frac{1}{50} \)
- Calculate the percentage: Multiply the result by 100.
\( \text{Concentration} = \frac{1}{50} \times 100 = 2 \)
Result
The calculated concentration is 2% (mass by volume).
