Ok so here's the story. I just bought a whole lot of darkroom stuff out of denver, Included in this buy was a lot of dry chemicals. the largest box of chem was a 9lb box of D-76. obviously i don't wanna mix all of it at once, i couldn't use it all before it went bad. so the nut of my question is I've figured that to mix dry D-76 at a liter at a time the ratio would be 104.675g of D-76 per liter. I want to know if anyone else has had experience doing this and if my math is correct. I'm pretty confident in my math, but i've only relied on pre-measured chems on the past. any comments or precautions?
