Answer 2

Answer

HOPE IT HELPS

Explanation:

One mole of NaOH weighs 23(Na)+16(O)+1(H)=40 g

A 0.5 M NaOH is then 20 g NaOH/L.

So dissolve 20 g NaOH in 500 ml water let it cool down to room temperature and fill it up to one liter. For accurate results you can use an analytical balance and a volumetric flask.
