Answer : The volume of 6M NaOH stock solution is, 16.7 mL
Explanation :
To calculate the volume of NaOH stock solution, we use the equation given by neutralization reaction:

where,
are the molarity and volume of NaOH stock solution.
are the molarity and volume of NaOH.
We are given:

Putting values in above equation, we get:

Thus, the volume of 6M NaOH stock solution is, 16.7 mL
I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:
