The strengths of 5 . 6 volume hydrogen peroxide (of density 1 g / mL ) in terms of mass percentage and molarity M respectively, are: (Take molar mass of hydrogen peroxide as 34 g / mol )

Options

A1.7 and 0.5
B0.85 and 0.25
C1.7 and 0.25
D0.85 and 0.5

Correct answer

A. 1.7 and 0.5

Step-by-step solution

For H 2 O 2 Molarity = Volume   strength 11 . 2 = 5 . 6 11 . 2 = 0 . 5   M Molarity % w / w × 10 × d GMM 0 . 5 = % w / w × 10 × 1 34 % w / w = 0 . 5 × 34 10 = 1 . 7
