Sorry Jim - the point I was (so clumsily) making is that 26gm salt and 100gm water isn't a 26% solution the % calc will be:
salt / (water +salt) * 100
Not that it really matters.
My brain then thought about whether the 100° brine is 26.395% by weight (gm) or by volume (ml), or whether the two are interchangeable. i.e. does 26.395gm of salt equal 26.396
ml when dissolved? I don't know why! It's not relevant! I can't help it!
It's just how my stupid brain works!
