How many grams of nitrogen are needed to produce 460g of ammonia

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

The element that has the greatest electronegativity is
