Preservative help??

So I got my hands on geogard 221 and planning on using it on my flaxseed gel. The instructions say that 0,5%-1% should be used...but how do I calculate it????
TIA!!

For easy math, say you want to make a 500 gram batch of gel. Your formula will be ...
Gel......................99% ......495 grams
Preservative ........ 1% ......... 5 grams
Total...................100% ..... 500 grams
Good luck!
