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.
