Answer:
532 moles of O atoms.
Explanation:
Given data:
Number of moles of oxygen atom present = ?
Number of molecules of N₂O₅= 6.41×10²⁵ molecules
Solution:
First of all we will calculate the number of moles of N₂O₅.
1 mole = 6.022×10²³ molecules
6.41×10²⁵ molecules × 1 mol /6.022×10²³ molecules
106.4 mol
Number of atoms of O:
1 mole of N₂O₅ contain 5 moles of O atoms.
106.4×5 = 532 mol
Answer:
Forests prevent desertification.
Explanation:
B.
(2.43*10^24)*1/(6.022*10^23)
C. development of a liquid propulsion system is the answer
Answer:
Our world will never be the same. Our beaches will be submerged, many towns, cities, states, and even countries will be partially if not completely submerged. All these human cities being flooded will kill thousands of people, pollute the ocean, and lose billions of dollars.
