Answer 2

Answer:

The sodium chloride equivalent, E, measured is $0.0125g$.

Therefore, option a) $0.0125g$ is correct.

Explanation:

Given,

The molecular weight of the drug, M = $340g/mol$

The given value of freezing point depression, $L_{iso}$ = $0.25$

The equivalent of the sodium chloride, E =?

As we know,

• The sodium chloride equivalent can be calculated by the formula given below:
• E = $\frac{17L_{iso} }{M}$

After putting the given values in the equation, we get:

• E = $\frac{17\times 0.25 }{340}$
• E = $0.0125g$

Hence, the equivalent of sodium chloride, E = $0.0125g$.
