Final answer:
To convert 0.840 quarts to milliliters, we multiply by the conversion factor of 946.353 mL per quart, resulting in approximately 795 mL. The closest given option is 790 mL.
Step-by-step explanation:
The question asks how many milliliters (mL) of lemonade a container that holds 0.840 quarts will hold. To solve this, we need to convert quarts to milliliters. First, we know that 1 quart is approximately 946.353 mL. So we can set up a conversion as follows:
0.840 qt × 946.353 mL/qt = 794.53652 mL
Since we are looking for an answer rounded to the nearest whole number, the proper conversion will be approximately 795 mL. Therefore, the closest answer from the multiple-choice options given is 790 mL, which is option c.
