Answer 1

The correct answer here is option c) 0.05 mg(milligram)

Explanation:

Answer 2

The correct answer here is option c) 0.05 mg(milligram)

Explanation:

The first step here to calculate the milligram of active ingredient in a 5% solution per milliliter is to assume that Z milligram of active ingredient is present in the 5% solution per milliliter.

NOTE* - milligram ( mg) and milliliter (ml)

so therefore, the equation would become,

5\% = \frac{Z mg}{1 ml}

.05 = \frac{Z mg}{1 ml}

.05 x 1 = Z mg

therefore there is .05 mg of active ingredient in the 5% solution per ml.
