Answer: The concentration of solution is 0.342 M

Step-by-step explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}* 1000}{\text{Molar mass of solute}* \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (Sodium chloride) = 15 g

Molar mass of sodium chloride = 58.5 g/mol

Volume of solution = 750 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=(15g* 1000)/(58.5g/mol* 750mL)\\\\\text{Molarity of solution}=0.342M$

Hence, the concentration of solution is 0.342 M
