What is the final molarity of a solution when 250 mL H2O is added to 150 mL
0,040 M NaOH(aq)?


Sagot :

Answer:

0.015M is the final molarity of the NaOH solution

Explanation:

A solution of 0.040M NaOH is diluted from 150mL to 250mL + 150mL = 400mL. That means the solution is diluted:

400mL / 150mL = 2.667 times.

As the original solution has a concentration of 0.040M, the diluted solution has a concentration of:

0.040M / 2.667 =

0.015M is the final molarity of the NaOH solution
