A chemist needs 2,220 ml of potassium chloride to complete an experiment. She has 2 L. How many more liters does she need?

DerKrebs [107]

Answer:

0.220 L

Step-by-step explanation:

One liter is 1000 mL, so 2,220 mL is 2.220 L. Subtracting the 2 L on hand gives the additional amount required:

2.220 L - 2 L = 0.220 L
