What is the molarity of an aqueous sodium chloride solution if .33 mol NaCl is dissolved in 2.5 L of water

[From: ] [author: ] [Date: 11-05-16] [Hit: ]

could you explain it a bit to help me get it?Since you are given moles of NaCl and a volume in liters,0.33 mol / 2.5 L = 0.132 mol/L = 0.......

I'm not asking for you to do my homework, but I really just don't get this :/ Our teacher sucks, could you explain it a bit to help me get it?

Molarity has the units moles /L

Since you are given moles of NaCl and a volume in liters, just divide the moles by the volume to give you molarity:

0.33 mol / 2.5 L = 0.132 mol/L = 0.132 M
