guys i read something and i dont have much knowladge can you help me ?
its says carbon black content ( mass ratio ) of 0.3% what does that means ? if i want 250 grams of some substance(PbO2) what is the mass ratio of 0,3 % in grams carbon black.
for example if i want to know how much carbon black i should put in in grams with 0,3 % mass ratio in 250 grams total (with Carbon black added) of PbO2 is that means carbon black grams = ( 0,3 % x 250 g ) / 100 ? is it means 0,75 grams of carbon black should be added to 249.25 grams of PbO2 ?
