First calculate the number of moles. Molar mass of Calcium
= 40.08 g/mol
Number of moles = 169 g / (40.08 g / mol) = 4.217 moles
Using Avogadros number, we can get the number of atoms:
<span>Number of atoms = 4.217 moles * (6.022 x 10^23 atoms /
moles) = 2.54 x 10^24 atoms</span>
Answer:
10.2 moles of oxygen which is 163.1 grams
Explanation:
Answer:
6.0x
molecules CO2
Explanation:
Take mass times molar mass times Avogadro's number

<h3><u>Answer;</u></h3>
- Fish respiring and releasing carbon dioxide into the water.
- Mixing occurring at the surface of the ocean with the atmosphere.
<h3><u>Explanation;</u></h3>
- <em><u>Ocean absorb carbon dioxide in a number of ways. Fish and other animals in the ocean take in oxygen and give off carbon dioxide into the water. Ocean plants respires using oxygen and release carbon dioxide into the water.</u></em>
- <em><u>Oceans also absorbs carbon dioxide from the atmosphere when the air meets water. Wind causes waves and turbulence, giving more opportunity for eater to absorb the carbon dioxide. </u></em>
