Answer:
426 mg = 4.26 x 10² mg
Explanation:
1 cup = 237.6 mL x 1 L/1000 mL = 0.2376 L
We divide the liters of milk the student drinks into the volume in liters of a cup to calculate the number of cups the student drinks per day:
number of cups per day = 0.318 L/0.2376 L = 1.34 cup
Now, we multiply the number of cups by the amount of calcium that a cup of milk has:
amount of calcium = 1.34 cup x 318 mg = 426 mg = 4.26 x 10² mg
Therefore, the student gets 426 mg (or 4.26 x 10² mg) of calcium in one day.
