The atomic mass of nitrogen is 14 g/mol. The atomic mass of hydrogen is 1 g/mol. When the reaction produces 68 grams of ammonia, how many grams of nitrogen were present initially? 4 112 56 12

forgot to add Nitrogen gas and hydrogen gas react to produce ammonia according to the following equation. N2 + 3H2 → 2NH3

@Loren Olson You said that "Your mass changes depending on gravity, but weight always remains the same." Im not sure but, i remember learning that mass can not change, but weight can. Weight can change based off of gravity but mass will always stay the sa...
