Question

If a prescription is written for 90 GM, how many ounces would you dispense?

1) 1
2) 3
3) 5
4) 7oz

Answer 1

To convert 90 grams to ounces, divide by the conversion factor of 28.35 grams per ounce, resulting in approximately 3.17 ounces. Thus, the answer to the student's question is 3 ounces, which is option 2.

Step-by-step explanation:

The student's question involves the conversion of grams (GM) to ounces. To answer the question of how many ounces would be dispensed if a prescription is for 90 grams, one must understand the conversion factor between grams and ounces. There are approximately 28.35 grams in an ounce. Thus, to convert 90 grams to ounces, the following calculation is needed:

90 grams ÷ 28.35 grams/ounce = 3.17 ounces

The closest whole number to 3.17 is 3, so the correct answer is option 2) 3 ounces.

When converting from a smaller unit to a larger unit, you divide, as seen in the cough syrup example provided where a chemist is checking the accuracy and precision of machines dispensing cough syrup measured in both milliliters and ounces. The principle is the same when converting from grams to ounces.
