Answer:
The correct answer is 0.89 mol.
Explanation:
At STP (Standard Temperature and Pressure) conditions, 1 mol of an ideal gas occupies a volume of 22.4 L. If we assume STP conditions, we can consider a convertion factor of 1 mol/22.4 L to convert the volume of NO₂ from liters to moles:
20,00 L x 1 mol/22.4 L = 0.89 mol
So, at STP, we would have 0.89 mol of NO₂
Answer: A
Explanation
The digestive tract carries out the function of peristalsis by moving food through the system. Peristalsis also removes excess liquid from the body. Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis. Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.
