Compare this ratio to the experimental number of moles computed above. The limiting reactants is/are

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.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
