Give the concentration in meters when 3.51 moles of HNO3 are dissolved in enough water to make 1.2 liters of solution
You are in great trouble. You are not taking notes, nor or reading the text, and yet you are taking chemistry.
Look up Molarity. You will fail chemistry if you do not know about Molarity, M.
M=molessolute/literssolution=3.51/1.2= you do the division.
