A)What mass of ammonia gas can be produced from a reaction between 565.0g H2 and 880.0g of N2 though the Haber-Bosh reaction? B) What mass of the excess reagent remains?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answers would be

the first one and the second one
