Answer to Question #163003 in General Chemistry for yara

Question

calculate the volume needed to prepare 500 ml of 0.2M NaOH from stock solution Have a concentration of 2N

Answer 1

Solution:

Normality (N) is a definition of concentration that depends on the specific reaction involved. For NaOH, 1 N is equal to 1 M. So,

500 mL $\dfrac{(0.2M)}{2M}$ = 50 mL

So, you will dilute 50 mL of 2 M NaOH to 500 mL.
