Calculate the mass of NaOH required to make 500ml of 0.5 M aqueous solution (Molecular mass of NaOH=40)
Answered by Shenaya
NaOH mols=0.5*500

NaOH mass required=0.5*500*molecular mass of NaOH
Answered by Damon
500 mL is HALF a liter. Therefore .5 + 40 = 20 grams
Answered by Shenaya
typo: mass required=0.5*(500*10^-3)*40 g
