Question

Determine volume strength of 0.45M H,O2

Answer 1

Answer:

hope it would be helpful for u

Explanation:

The balanced reaction is as follows:

2H

2

O

2

→2H

2

O+O

2

−1 −2 0 (oxidation state of O)

So, 2 moles of H

2

O

2

gives 1 mole of O

2

.

Therefore, 1 mole of H

2

O

2

will give 11.2 L of O

2

gas.

So, volume strength of H

2

O

2

=11.2× molarity.

Hence, for 1 M H

2

O

2

, volume strength is 11.2.
