Question

9. IN Naoh to prepare 250 ml volume how many grash of Naoh needed?
​

Answer 1

Answer:

Approximately the gfm, or gram formula mass, of NaOH is 40 g/m, so

.5 m NaOH * 40 g/m NaOH= 20 g NaoH

In this case the mL of the solution is irrelevant but in case if the mols(m) were meant to be molarity(M) then

250 mL=>.25 L *.5 m/L=.125 m NaOH * 40 g/m NaOH= 5 g NaOH
