Question

117 grams of NaCl are dissolved in water to make 500 mL of solution. Water is then added to this solution to make a total of one liter of solution. The final molarity of the solution will be?

Answer 1

`"Option b"`

Explanation:

`"Molarity"` `=` `"Moles of solute"/"Volume of solution"`, and so we work out the quotient.....

`((117*g)/(58.44*g*mol^-1))/(1*L)=???*mol*L^-1`.

The initial dilution was there to distract you. We only need the final volume, and the amount of solute dissolved INITIALLY.
