25.0g of NaCl is placed in a 100.0ml volumetric flask. Enough water is added to dissolve the salt and then the volume is brought to 100.0ml total. What is the molar (moles/L or M) concentration of the NaCl?

Answer : The molar concentration of in the solution is, 4.27 M

Explanation : Given,

Mass of = 25.0 g

Volume of solution = 100.0 mL

Molar mass of = 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 :

Now put all the given values in this formula, we get:

Therefore, the molar concentration of in the solution is, 4.27 M

i think it is true since you can test the answer and can use observations to complete it.
