1 molecule of oxygen = 2 atoms of oxygen
1 molecule of ozone = 3 atoms of oxygen
In flask P, 1 mole of oxygen gas = 6.022 X10231023 molecules
.'. 0.5 mole of oxygen gas = 6.022X 10231023 x 0.5 molecules= 6.022X 10231023 x 0.5x 2 atoms
= 6.022 x 10231023 atoms
In flask Q, 1 mole of ozone gas = 6.022 X 10231023 molecules
0.4 mole of ozone gas = 6.022 X 10231023 X 0.4 molecules = 6.022 X 10231023 X 0.4 X 3 atoms
= 7.23 X 10231023 atoms
.'. Flask Q has greater number of oxygen atoms as compared to the flask P.

Answer 2

Answer:

1 molecule of oxygen = 2 atoms of oxygen

1 molecule of ozone = 3 atoms of oxygen

In flask P, 1 mole of oxygen gas = 6.022 X10231023 molecules

.'. 0.5 mole of oxygen gas = 6.022X 10231023 x 0.5 molecules= 6.022X 10231023 x 0.5x 2 atoms

= 6.022 x 10231023 atoms

In flask Q, 1 mole of ozone gas = 6.022 X 10231023 molecules

0.4 mole of ozone gas = 6.022 X 10231023 X 0.4 molecules = 6.022 X 10231023 X 0.4 X 3 atoms

= 7.23 X 10231023 atoms

.'. Flask Q has greater number of oxygen atoms as compared to the flask P.
