For 1 l of water you can calculate the required amount of KOH pills (X) to achieve the desired concentration in wt% (Y) by: | For 1 l of water you can calculate the required amount of KOH pills (X) to achieve the desired concentration in wt% (Y) by: | ||
X=(Y∙1000g)/(0.85-Y) | <math>(0.85 ∙X)/(X+1000g)=Y</math> | ||

So for a 10wt% solution you will need 133 g pills for each liter of water. | So for a 10wt% solution you will need 133 g pills for each liter of water. | ||
