Question

Calculate mass of NaoH required to make 500ml of 0.5molar solution (molecular mass of NaoH=40

Answer 1

Molarity=moles of solute/ltr of solution

0.5=x/40×1000/500 (x=mass of NaOH req,40=molecular mass of NaOH, 500=volume given in ml)

*volume given is converted into ltr

0.5=x/20

0.5×20=x

Therefore, 10 g of NaOH is required

Answer 2

hey friend here is your answer..... ⛄⛄


$10 \: g \:$
of NaOH is required.
