Question

A solution is made by dissolving 0.60 mol of NaCl in enough water to give a final volume of 300.0 mL. What is the molarity (M) of the solution?

Group of answer choices

0.018 M

2.0 M

0.18 M

0.2 M

Answer 1

Given that

Number of moles of NaCl = 0.60 mol

Volume of the solution = 300.0 mL = 0.300 L

We know that

Molarity = moles/volume in L = 0.60 mol/0.300 L = 2.0 M

Molarity of the NaCl solution = 2.0 M

Option B is the right answer.
