19.8

Rationale: By using Clark's rule, first convert kilograms to pounds: 1 kg = 2.2 lbs. Use this formula: 1 kg / 2.2 lbs = 18 kg / X lbs. X = 39.6 lbs. Substitute into the equation: 39.6 / 150 x 75 mg = 19.8 mg.

Rubber

Rationale: A rubber spatula should be used in measuring corrosive ingredients. This is because a steel or plastic spatula may react with the ingredients. Wood has its own corrosive properties and should not be used.
