# 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?

$\text{Option b}$

#### Explanation:

$\text{Molarity}$ $=$ $\text{Moles of solute"/"Volume of solution}$, 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.
