1.	31. How will you prepare M/10 and M/20 solutions of NaOH in 250 ml of water
Answer» Answer: Normally, solution percentages are defined as weight(solute)/weight(solution) or weight(solute)/volume(solution). So 60% NaOH solution should be 60g NaOH and 40g H20 (if w/w) or FILLING up 60g NaOH with water until you reach a TOTAL volume of 100ML (if w/v).
