Ning is a little confused.
with TFSE, it seems that with solids (i.e. NaOH), "percent" means "grams of solid per grams of solution", weight/weight.
But with nominally gaseous things (ammonia), Strange, hard to isolate things (NaOCl), what does "percent" mean?
Ning has heard the term "w/v" fly around, but how can a weight divided by a volume give a percentage?
And what is the "weight" of dissolved gasses like ammonia?
Ning knows these are simple-minded questions, but for a newbee, they are essential. Perhaps ning could be directed to a suitable FAQ?
Ning wants an algorithm to convert: percent solution --> molarity
With w/w, it is relatively easy.
but....
Thanks in advance, bees.
