<span>(6.36x10^25)/(6.02*10^23) is approximately 105.6 moles</span>
Answer: A & D
Explanation:
The two main forces are temperature and salinity.
Answer:
- <u><em>1.12 liters</em></u>
Explanation:
<u>Calculating number of moles</u>
- Molar mass of O₂ = 32 g
- n = Given weight / Molar mass
- n = 1.6/32
- n = 0.05 moles
<u>At STP</u>
- One mole of O₂ occupies 22.4 L
- Therefore, 0.05 moles will occupy :
- 22.4 L x 0.05 = <u><em>1.12 L</em></u>
your answer is c. two atoms of oxygen.
