200 mL of an 8M NaOH solution is more concentrated than 500 mL of a 4M NaOH solution.
Molarity of a solution defines the concentration of a solution. It is the amount of the solute in 1 L of water. Mathematically it is expressed as:
[tex]Molarity = \frac{Mole}{Volume}[/tex]
From the formula above, the molarity and the volume are in inverse proportionality.
Thus, an increase in the volume of water will leads to a decrease in the concentration while a decrease in the volume of water will lead to an increase in the concentration.
We shall compare both solutions as follow:
Solution 1:
Volume = 200 mL
Molarity = 8 M
Solution 2:
Volume = 500 mL
Molarity = 4 M
We can see that solution 1 has a lower volume than solution 2. Hence, the concentration of solution 1 is more than that of solution 2.
From the illustrations above, we can conclude that 200 mL of a 8M NaOH solution is more concentrated than 500 mL of a 4M NaOH solution.
