<span>1 mole of any substance contain Avogadro's number of molecules so we can calculate the number of moles by dividing the provided number of atoms over Avogadro's number to obtain the number of moles
Answer : 19.9 moles of phosphorus
Solution : Atoms / Avogadro's number (6.022 x 10</span>²³<span> atoms/mol)
1.20 x 10</span>²⁵<span> atoms / 6.022 x 10</span>²³<span> = 19.927</span>
Answer:
Explanation:
Deepwater currents are formed, when the water becomes denser, surface water is cool. and movement of water below the surface.
- Currents are caused by differences in <u>density, temperature, and salinity.</u>
- The water along the surface forms wind currents, and deep currents are caused by differences in temperature and salinity.
Hope this helps you!
Good Luck with your Assignment!
