RE: [compost_tea] RE: Baking Soda

Percent by volume: Solutions based on percent by volume are calculated the same as for percent by weight, except that calculations are based on volume. Thus one would simply determine what percentage was desired (for example, a 20% by volume aqueous solution of sodium chloride) and the total quantity to be prepared.

If the total quantity needed is 1 liter, then it would simply be a matter of calculating 20% of 1 liter which, of course is:

0.20 NaCl * 1000 ml/l = 200 ml NaCl/l.

Tom: As I read through the article, How do you make a 2% backing soda solution? What does this 2% mean?
