i was just reading about using the molar mass and valance to work out strochiometic rations. i was working through some examples but was a cant find is how to calculate the valances of molecules.
for instance KClO4 has a valance of -8, NH4NO3 has a valance of -2, i know this because these values were provided, but how are they calculated? and what about for more complex fuels like heximine etc?
