How many grams of dibasic acid (molecular mass = 200) should be present in 100 mL of its solution to give decinormal strength?

Options:

Answer:

Solution:

Number of meq in 100 mL $\frac{N}{10}$ solution of a dibasic acid = NV
$= 100 \times \frac{1}{10} = 10$ meq
Mass of acid present $= \frac{N V \times E}{1000} = \frac{10 \times 200 / 2}{1000}$
$= 1$ g.
