Explanation:
W =mass of solute= 80g
M =molar mass of NaOH=23+16+2= 41g/mol
V=Volume of solution=4L
Hence
morality of solution=number moles of solute/volume of solution in L
=W/M × 1/V
=80/41 ×1/4
=0.48780 Molar (This is the molarity of solution)
Molarity is depends on volume. Therefore as Temperature increases, Molarity decreases as Volume decreases.
I hope this helps you!!
