Question

Out of 1 gram o2 1 gram o and 1 gram of ozone the maximum number of oxygen atoms are contained in

Answer 1

For 1gm O2,

Molar mass = 32gm

Moles = 1/32= 0.03125

No of atom = 2×0.03125×6.023× 10^23=3.76×10^22 atom of O

For 1gm O,

Molar mass = 16 gm

Moles = 1/16= 0.0625

No of atom= 0.0625×6.023× 10^ 23= 3.75× 10^22 atom of O

For 1 gm O3,

Molar mass = 48gm

Moles= 1/48= 0.0208

No of atom= 3×0.0208×6.024×10^23=3.76×10^22 atom of O

So all these options have same number of atom
