The table below displays four solutions made by dissolving salt in water.

solution a: 5.0g of salt 50.0ml of water
solution b: 5.0g of salt 75.0ml of water
solution c: 5.0g of salt 100.0ml of water
solution d: 5.0g of salt 125.0ml of water

To determine which solution has the highest concentration of salt, we can calculate the concentration for each solution using the formula:

\[ \text{Concentration} = \frac{\text{mass of solute}}{\text{volume of solvent}} \]

Concentrations for each solution:

  • Solution A: \[ \text{Concentration} = \frac{5.0 , \text{g}}{50.0 , \text{ml}} = 0.1 , \text{g/ml} \]

  • Solution B: \[ \text{Concentration} = \frac{5.0 , \text{g}}{75.0 , \text{ml}} \approx 0.0667 , \text{g/ml} \]

  • Solution C: \[ \text{Concentration} = \frac{5.0 , \text{g}}{100.0 , \text{ml}} = 0.05 , \text{g/ml} \]

  • Solution D: \[ \text{Concentration} = \frac{5.0 , \text{g}}{125.0 , \text{ml}} = 0.04 , \text{g/ml} \]

Based on these calculations, Solution A has the highest concentration of salt at 0.1 g/ml.

a, b, c, or d?

The solution with the highest concentration of salt is Solution A.
