◼HERE IS YOUR ANSWER◼

A) 1g of O

Because they will all contain the same amount of oxygen atoms as 1g|16 g per mole will always be .0625 moles of oxygen. however the greatest number of molecules will a) 1g of O atoms. 1/6= .0625, 1/32=.03125 moles of molecules for O2, and for O3 , 1/48 = .0208 moles of molecules.

we have formula
mole = no of particles / avagadro no
mole = given wt/ molecular wt
so increase in molecular wt results in decrease in mole and decrease in mole results in decrease in no of particles
so higher is the molecular wt lower is the particles
here o has molecular wt 16 which is least so in this situation it will have large no of particles
answer: A
