hi there bestie [i think its 3]
I don't have a calculator with me right now, but that mass would be 1200 grams. Divide the given amount of grams by the molar mass of NH3, which is 17.031g/mol. (Nitrogen + 3(hydrogen)). Again, sorry I didn't have a calculator. But all you would need to do is divide 1200 by 17.031. If you need to use sig figs, your answer should have 2 because the 1.2 x 10^3 limits your amount of sig figs.
Capsaicin is the chemical in the peppers, and then milk reverses it by using casein (A fat loving compound) to bond to the capsaicin and wash it away. Hope this helps!
