Question

What volume of a 2.5 M NaOH solution is required to make 1 liter of a 0.75 M NaOH

Answer 1

300 milliliters (0.3 liters) of a 2.5 M NaOH solution is required to make 1 liter of 0.75 M NaOH.

Answer 2

Answer: 0.3 liters

Step-by-step explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

According to the neutralization law,

`M_1V_1=M_2V_2`

where,

`M_1` = molarity of stock solution = 2.5 M

`V_1` = volume of stock solution = ?

`M_2` = molarity of diluted solution = 0.75 M

`V_2` = volume of diluted solution = 1 L

`2.5M* V_1=0.75M* 1L`

`V_1=0.3L=300ml`

Therefore, the 0.3 L of NaOH solution is required to make 1 liter of a 0.75 M NaOH.
