6. What is the molarity of a solution made from dissolving 3.0 moles of
NaCl in 250 mL of solution?
0.012 M Naci
750 M NaCl
O
3.0 M NaCl
O
12 M NaCI

The correct answer is 12 M

Explanation:

A molar solution indicates the moles of solute (NaCl in this case) in 1 liter of solution (1000ml).

250 ml solution3 moles of NaCl

1000ml solutionx= (1000ml solutionx3 moles of NaCl)/250 ml solution

x=12 moles of NaCl---> 12 M
