If 1mole ------------- is ---------------- 6.02*10²³
than 0.25mole ----- is ---------------- x
x = [0.25mole*6.02*10²³]/1mole = <u>1,505*10²³</u>
Answer:
Oxygen.
Explanation:
They take in oxygen from the air. This is the process of respiration.
Since the exponent is negative, you move the decimal (2.0) to the left two spots leaving you with .02
