For an order of Glucophage at 1 gm, how many tablets are needed if each tablet is 500 mg?

To determine the number of tablets needed for an order of 1 gram of Glucophage when each tablet contains 500 mg, it's essential to convert grams to milligrams since the tablet dosage is provided in milligrams.

1 gram is equivalent to 1000 milligrams. Therefore, when you need 1 gram (1000 mg) of Glucophage and each tablet is 500 mg, you can find the number of tablets required by dividing the total dosage needed (1000 mg) by the dosage per tablet (500 mg):

1000 mg ÷ 500 mg/tablet = 2 tablets.

This calculation shows that to achieve a total of 1000 mg, which is 1 gram, you would need 2 tablets of Glucophage. Hence, the choice indicating 2 tablets accurately reflects the requirement based on the provided information.
