The correct answer is "85.71 mg".

Explanation:

The given values are:

Mass of drug,

= 3.0 mg

Mass percentage,

= 3.5%

As we know,

⇒ $Mass \ percent = \frac{Mass \ of \ drug}{Mass \ of \ solution}\times 100$

Or,

⇒ $Mass \ of \ solution = \frac{Mass \ of \ drug}{Mass \ percent}\times 100$

On substituting the values, we get

⇒ $=\frac{3.0}{3.5}\times 100$

⇒ $=0.8571\times 100$

⇒ $=85.71 \ mg$
