How much talc is needed to fill this order for 120g total final product? Nuprcainal 4% Zinc Oxide 20% Talc 2%

  1. 1200mg

  2. 1500mg

  3. 2000mg

  4. 2400mg

The correct answer is: 2400mg

For this question, it is important to remember that grams (g) and milligrams (mg) are different units of measurement. The order is asking for a final product of 120 grams, but the choices are listed in milligrams. This means that the correct answer must be converted from grams to milligrams before comparing it to the choices. The incorrect choices are all in milligrams and are too small to fill the order for 120 grams. For example, 1200mg is only 1.2 grams and would not be enough. 2400mg, the correct answer, is equivalent to 2.4 grams which is enough to fill the order for 120 grams.
