교과서 질문
Solve each of the following problems using one or more conversion factors: a. A container holds 0.500 qt of liquid. How many milliliters of lemonade will it hold?
검증된 단계별 안내1
Identify the conversion factors needed: 1 quart (qt) is equivalent to 946.353 milliliters (mL).
Set up the conversion by writing the given quantity (0.500 qt) and multiply it by the conversion factor to cancel out quarts and convert to milliliters.
The conversion setup will look like this: 0.500 \(\text{ qt}\) \(\times\) \(\frac{946.353 \text{ mL}\)}{1 \(\text{ qt}\)}.
Perform the multiplication to convert the volume from quarts to milliliters.
Ensure the units of quarts cancel out, leaving the result in milliliters.
