Option 3rd (15%)
Percentage strength of 50 volume
solution is 15%.
Explanation:
On decomposition of ,
and
molecule is produced.
50 volume solution means that 1 L of 50 volume
on decomposition gives 50 L of
at NTP.
2(2+32)g 22.4 L at NTP
68 g
22.4 L of at NTP is produced from = 68 g of
solution
∴ 50 L of at NTP is produced from =
=
g of
solution
But 50 L of at NTP are produced from 1 L of 50 volume
solution.
∴ Strength of solution in 50 volume
=
g
Percentage strength of solution =
= 15 %
So, the Percentage strength of 50 volume solution is 15%.
