Question

With a 0.5 M solution: How many moles of NaCl would there be in 1,000 ml?

Answer 1

Answer: The number of moles of sodium chloride in the solution is

Explanation:

Molarity of the solution is defined as the number of moles that are present in one liter of solution.

The equation used to calculate the molarity of the solution follows:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}\text{Volume of solution (in L)}}$

We are given:

Volume of solution = 1000 mL = 1 L   (Conversion factor: 1 L = 1000 mL)

Molarity of the solution = 0.50 moles/ L

Putting values in above equation, we get:

$0.5mol/L=\frac{\text{Moles of solute}}{1L}\\\\\text{Moles of the solute}=0.5mol$

Hence, the number of moles of NaCl in solution is 0.5 moles.

Answer 2

0.5 moles, though not a verified answer hope it helps! :D
