About Trizol

I want to make some homemade Trizol. However I find something very wired in the protocols in Openwetware([[1]]). In protocols Guanidinium Thioyanate(W.M. 118.2) final concentration is 0.8M, but 118.2g is used in 1L Trizol. Ammonium thiocyanate (W.M. 76.1) is 76.1g in Trizol, however, they said the final concentration is 0.4M. I can not understant that. Thank you for your answer!
