To determine which solution is the most concentrated, we need to calculate the concentration of each option. Concentration is typically expressed as the amount of solute per unit volume of solvent, commonly in grams per milliliter (g/ml).
- 2.4 g solute in 5 ml solvent:
- Concentration = 2.4 g / 5 ml = 0.48 g/ml
- 20 g solute in 50 ml solvent:
- Concentration = 20 g / 50 ml = 0.4 g/ml
- 2.4 g solute in 2 ml solvent:
- Concentration = 2.4 g / 2 ml = 1.2 g/ml
- 50 g solute in 175 ml solvent:
- Concentration = 50 g / 175 ml = 0.2857 g/ml
- 30 g solute in 150 ml solvent:
- Concentration = 30 g / 150 ml = 0.2 g/ml
Now, comparing the concentrations we calculated:
- 2.4 g in 5 ml: 0.48 g/ml
- 20 g in 50 ml: 0.4 g/ml
- 2.4 g in 2 ml: 1.2 g/ml
- 50 g in 175 ml: 0.2857 g/ml
- 30 g in 150 ml: 0.2 g/ml
The most concentrated solution is option c) 2.4 g solute in 2 ml solvent, with a concentration of 1.2 g/ml.
