Question

A student needs 200ml of 1 M NaOH for an experiment. The stockroom has 12 M NaOH only. How can the student prepare 1 M NaOH from the 12 M available?

Answer 1

Try using the formula M1V1=M2V2

where M is the Molar n V is the volume. Change 200ml into 0.200L

subs in value.
0.200(1)=12(V)
V= 0.017L

Hence u need 0.017L of 12M NaOH to equivalent with 200mL of 1M NaOH.
