Question

Which is more concentrated 200 ML of an 8-M NaOH solution or 500 mL of a 4-M NaOH solution

Answer 1

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:

$Molarity = \frac{Mole}{Volume}$

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.

Answer 2

Answer:

200 ML of an 8-M NaOH solution; The higher the molarity, the higher the concentration of the substance. The volume of the 8M NaOH solution is less as well.
