How many grams of solid NaOH are required to prepare 500 ml of a

0.04 M solution? (b) Express the concentration of this solution in terms of
N, g/liter, % w/v?

3 answers

0.02 moles is required=0.5L*0.04 M

500mL=0.5L

0.02 moles*(39.997g/mole)=???

(???/500)*100= w/v %
Only 1 equivalent. So, M is equal to N

g/L= ???/0.5L

Answer should have only one significant figure, but you can include 3.
