Yes,

You will need 10 ml, not 100 ml, to make 20% solution.

Good luck.

The chloroplatinite is in powder form. I have 2 grams of it. I have to make the solution by adding only water I assume. In the previous thread they talk about using 100ml of water, but doesn't this give you a 2% solution (2g/100ml= 2%)?

Wouldn't I have to mix 2 grams of chloroplatinite with 10ml of water to get a 20% solution?
