How much do I dilute HASA chlorine to make household bleach?
Chlorox is 5%

When I tried to figure out the answer on my own, I found that the percent
is different whether it's a percent by volume or a percent by weight or
even a percent by "trade percent" (whatever that is).

All these different ways of measuring percent are confusing to me which is
why I asked the question.

This reference said the MSDS for "Clorox Regular Bleach" says it's 6.15%
sodium hypochlorite.

But that still doesn't tell me which percent that is (by weight? by volume?
by available ppm of sodium hypochlorite?) so the numbers can be off by a
huge amount since I'd be comparing apples to oranges to bananas (weight
versus volume versus reactivity).

Then bear in mind it starts losing strength the moment it is made,
based on how it is stored.
