A compounded prescription calls for 600 gm of white perolatum. How many 1 lb jars should you obtain?

To determine how many 1 lb jars are needed for 600 grams of white petrolatum, it is important to first convert the weight from grams to pounds, since the jar capacity is given in pounds.

One pound is equivalent to approximately 453.59 grams. To find out how many pounds 600 grams is, you can use the conversion factor:

600 grams ÷ 453.59 grams/pound ≈ 1.32 pounds.

Now that we know the total weight of the prescription is approximately 1.32 pounds, we need to calculate how many jars are required. Since each jar holds 1 pound, you would need to round up the number of jars to ensure you have enough to hold all 600 grams.

Given that 1.32 pounds is more than 1 jar but less than 2, you will need 2 jars to contain the full amount of white petrolatum. This rounding up method ensures that you will not be short on the amount required for the compounded prescription.

Therefore, obtaining 2 jars of 1 lb each is the correct decision for this scenario.
