Part A) In the reaction shown here, 4.58 L of O2 forms at P=745mmHg and T=308K. How many grams of Ag2O decomposed? 2Ag2O(s)→4Ag(s)+O2(g)

Part B)
In the reaction in Part A, what mass of Ag2O(s) (in grams) is required to form 388 mL of oxygen gas at P=734mmHg and T=25∘C?

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 increase of protons   hope this

girl imma just put my comment here because i need a couple point okurrttt
