Answer : The molar concentration of [tex]NaCl[/tex] in the solution is, 4.27 M
Explanation : Given,
Mass of [tex]NaCl[/tex] = 25.0 g
Volume of solution = 100.0 mL
Molar mass of [tex]NaCl[/tex] = 58.5 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
[tex]\text{Molarity}=\frac{\text{Mass of }NaCl\times 1000}{\text{Molar mass of }NaCl\times \text{Volume of solution (in mL)}}[/tex]
Now put all the given values in this formula, we get:
[tex]\text{Molarity}=\frac{25.0g\times 1000}{58.5g/mole\times 100.0mL}=4.27mole/L=4.27M[/tex]
Therefore, the molar concentration of [tex]NaCl[/tex] in the solution is, 4.27 M
