The correct answer is option B.
Explanation:
Mass of
= 44.18 g
Moles of
According to reaction , 2 moles of
is formed from 3 moles of oxygen.
Then from 0.4331 moles of
moles of oxygen gas formed will be:
In order to find the volume of the oxygen gas we will use ideal gas equation:
Hence, the correct answer is option B.
