Mixing sodium chlorite powder

I have a white bottle of sodium chlorite powder 80%. I hv had it for a while but lost the directions on how to mix it. I don't know the weight of the bottle or how much is in it.
What is the ratio of water to powder in cups or oz? Tia

Hi , Tia. Welcome to the Forum!
The only way to get an accurate mix is by weight:

28 units 80% sodium chlorite + 72 units distilled water = 100 units @ 28%
