Ksivusya [100]

Answer:

5.85 gm.

Explanation:

We know that,

Normality =<u> Molarity × Molecular </u><u>weight</u>

Equivalent weight

Since molecular weight of NaCl= equivalent weight = 23+35.5 =58.5

Normality of NaCl= molarity=2

Now,

Normality= <u>weight</u><u> </u><u>in</u><u> </u><u>gram</u><u> </u><u>×</u><u>1000</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

Volume ×equivalent weight

Weight in gram is given by,

<u>=</u><u>Normality × Volume × equivalent </u><u>weight</u>

1000

= <u>2× 50 × 58.</u><u>5</u>

1000

=5.85 gm.
