Answer:
Um did you post something I don't see nothing
Explanation:
I believe the best answer is D.
All answers contribute to a machine, if there is an all above choice, chose that.
the concentration when 0.065 moles of NaNO3 are dissolved in enough water to make 150 ml of solution is calculated as follows
concentration (molarity) = moles/volume x1000
molarity is therefore= 0.065moles/ 150 x1000 = 0.43M
