For the following hypothetical reaction: 3A + 12B --> 3C

How many moles of B will you need to convert 5 moles of A into as many moles of C as possible?

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 volume increases
