d) 0.29lb

Answer 1

To convert from pounds to grams, the student lab assistant does not have enough of the compound is o.28lb. The correct option is a.

Step-by-step explanation:

To convert from pounds to grams, we can use the conversion factor that 1 pound is equal to 453.592 grams. Therefore, the 1/4 lb bottle is equal to 453.592/4 = 113.398 grams. Since the student needs 125 grams of the compound, the student does not have enough of the compound.

To convert the 125 grams to pounds, we can divide by the conversion factor of 453.592 grams per pound. 125/453.592 ≈ 0.2753 lb. Therefore, the student needs approximately 0.28 lb of the compound. Therefore, the answer is option a) 0.28 lb. The correct option is a.
