Final answer:
The given unit for the problem is gallons, and the needed unit is liters. To convert 2.5 gallons to liters, you use the conversion factor that 1 gallon is approximately equal to 3.79 liters, resulting in about 9.475 liters of blood in a 2.5-gallon bag.
Step-by-step explanation:
To determine how many liters of blood are in a full 2.5-gallon blood bag, we first need to recognize the given units and the needed units. The given unit in the problem is gallons, as the quantity of the blood bag is already known in gallons. The needed unit is liters because we are required to find out how much blood is in the bag in terms of liters.
Converting Gallons to Liters
The conversion factor between gallons and liters is that 1 gallon is approximately equal to 3.79 liters. To convert from gallons to liters, multiply 2.5 gallons by the conversion factor:
2.5 gallons × 3.79 liters/gallon = 9.475 liters
Therefore, a full 2.5-gallon blood bag contains about 9.475 liters of blood.
