11.2 lit contains 0.5 moles of oxygen. .
no. of oxygen molecule= 6.022×10²³×0.5
no of oxygen atom=2×0.5×6.922×10²³( because each oxygen molecule has 2ocygen atoms)
= 6.022×10²³

Answer ________________________ 6.022×10^23 number of oxygen atoms are present in 11.2 litre oxygen at NTP .
Explanation_________
No. of moles of oxygen,
n= Volume(litre) /22.4 litre
n = 11.2 / 22.4
= 0.5
Now , Number of oxygen atom present here is
= 2×0.5 × 6.022× 10^23
=6.022×10^23
