Question

flask A contains 0.5 mole of oxygen and flask B contains 0.4 mole of ozone.
1) whose flask is heavier.
2) How many particles are more in flask A or flask B.​

Answer 1

1) B flask is heavier

explanation- for o2 0.5×2 = 1.0 and for o3 0.4×3 = 1.2

OR

by mass

for o2 = 16 × 2 = 32 and for o3 16 × 3 = 48

therefore flask B will be heavier than flask A

2) particles k mean agr mole se h to

1.2 - 1.0 = 0.2

therefore 0.2 moles are more in flask B than in A
