Question

A given solution of H₂O₂ is 30 volumes. Its concentration in terms of molarity is ______.

Options

• 9.1 M

• 2.68 M

• 2.5 M

• 26.8 M

Answer 1

A given solution of H₂O₂ is 30 volumes. Its concentration in terms of molarity is 2.68 M.

Explanation:

VS = M × 11.2

30 = M × 112

∴ M = 2.68 M
