Final answer:
The total volume of the cough syrup prepared by the pharmacist, after mixing all components, is 3.525 liters.
Step-by-step explanation:
In the context of basic hot drinks, the number of pumps of syrup can vary depending on the specific drink and the size of the cup. Typically, hot drinks like coffee, tea, and hot chocolate are made with flavored syrup added to them. To find the total volume of the cough syrup mixture, we need to add the volumes of all the components together. The pharmacist mixes 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters of water. Remember, 1 liter is equivalent to 1,000 milliliters. Therefore, we first convert the volume of water from liters to milliliters:
1.25 liters = 1,250 milliliters
Now, we add all the milliliter values together to find the total volume in milliliters:
1,550 mL + 725 mL + 1,250 mL = 3,525 milliliters
Finally, to convert the total volume back to liters, we divide by 1,000:
3,525 milliliters ÷ 1,000 = 3.525 liters
The total volume of the mixed cough syrup is 3.525 liters.
