The amount of H_ 2 O_ 2 present in 1 litre of 1.5 N H_ 2 O_ 2...

The amount of

\mathrm{H}_{2} \mathrm{O}_{2}

present in 1 litre of

1.5 \mathrm{ N} \mathrm{H}_{2} \mathrm{O}_{2}

solution, is:

Options

A $25.5 \mathrm{ g}$
B $3.0 \mathrm{ g}$
C $8.0 \mathrm{ g}$
D $2.5 \mathrm{ g}$

Correct answer

A. $25.5 \mathrm{ g}$

Step-by-step solution

Molecular weight of

\mathrm{H}_{2} \mathrm{O}_{2}=34

Equivalent weight of

\mathrm{H}_{2} \mathrm{O}_{2}=17\therefore 1 \mathrm{ L}

1 \mathrm{ N} \mathrm{H}_{2} \mathrm{O}_{2} \mathrm{has}=17 \mathrm{ g}

\mathrm{H}_{2} \mathrm{O}\therefore 1

Lof

1.5 \mathrm{NH}_{2} \mathrm{O}_{2}

has

=1.5 \times 17=25.5 \mathrm{ g} \mathrm{of} \mathrm{H}_{2} \mathrm{O}_{2}
