Answer:
Since, 500ml solution contains 6.8g H2O2.
So, 10 ml solution contains 0.136g H2O2.
hence, mole of H2O2 = 0.136/34 = 0.004 mol.
Now, H2O2 decomposes as
2 H2O2 --------> 2 H2O + O2
So, mole of O2 gas formed = 0.002 mol
= 0.002 * 22.4 lit
= 0.0448 lit.
= 44.8 ml (ans)
So, (3) is correct answer.
