The following table displays four solutions created through the dissolution of salt in water.

Solution: A
Mass of NaCI (g): 5.0
Volume of Water(mL): 50.0

Solution: B
Mass of NaCI (g): 5.0
Volume of Water(mL): 75.0

Solution: C
Mass of NaCI (g): 5.0
Volume of Water(mL): 100.0

Solution: D
Mass of NaCI (g): 5.0
Volume of Water(mL): 125.0

Among the provided solutions, which one exhibits the greatest concentration of salt?

11 answers

To determine which solution exhibits the greatest concentration of salt, we can calculate the concentration of sodium chloride (NaCl) in each solution. The concentration (C) can be calculated using the formula:

\[ C = \frac{\text{mass of solute (g)}}{\text{volume of solvent (mL)}} \]

Let's calculate the concentration for each solution:

Solution A: \[ C_A = \frac{5.0 , \text{g}}{50.0 , \text{mL}} = 0.1 , \text{g/mL} \]

Solution B: \[ C_B = \frac{5.0 , \text{g}}{75.0 , \text{mL}} \approx 0.0667 , \text{g/mL} \]

Solution C: \[ C_C = \frac{5.0 , \text{g}}{100.0 , \text{mL}} = 0.05 , \text{g/mL} \]

Solution D: \[ C_D = \frac{5.0 , \text{g}}{125.0 , \text{mL}} = 0.04 , \text{g/mL} \]

Now comparing the concentrations:

Solution A: 0.1 g/mL
Solution B: 0.0667 g/mL
Solution C: 0.05 g/mL
Solution D: 0.04 g/mL

The solution with the greatest concentration of salt is Solution A, with a concentration of 0.1 g/mL.

so which one Is it?

The solution with the greatest concentration of salt is Solution A, which has a concentration of 0.1 g/mL.

is it solution A, B, C, or D

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

just put the letter

so its solution D?

No, the correct answer is A. Solution A has the greatest concentration of salt.

is it solution C?

No, the solution with the greatest concentration of salt is not Solution C; it is Solution A.

To clarify:

Solution A: 0.1 g/mL (highest concentration)
Solution B: 0.0667 g/mL
Solution C: 0.05 g/mL
Solution D: 0.04 g/mL

So the correct answer, with the highest concentration, is A.
