Answer:
There are 140.9 grams in 2.393*10²⁴ aotms of Cl.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole of the compound, 2.393*10²⁴ atoms are contained in how many moles?
amount of moles= 3.973
If the molar mass of Cl is 35.453 , then the amount of mass that contains 3.973 moles can be calculated as:
3.973 moles*35.453 = 140.85 grams ≅ 140.9 grams
<u><em>There are 140.9 grams in 2.393*10²⁴ aotms of Cl.</em></u>
Pulled apart (moved with the magnetic force)
The answer is the plate tectonics.
During the rock cycle, the sedimentary rocks return again to the interior earth and become metamorphic rocks by metamorphism, and then the metamorphic rock goes deeper and melt into magma by high temperature.
The plate tectonics movements and the changing in its rate we affect the production and destruction of the sedimentary, metamorphic and igneous rocks.
For example, the metamorphic rocks formed at a position of a compression at convergent plate boundaries, So by increasing the rate of plate tectonic movements the rate of formation of the metamorphic rocks will be increased also.
and sedimentary rocks which meanly moves by weathering and erosion also the plate tectonic affect its movement .as the plate tectonics affect Uplift of the crust areas because the uplift of the crust will occur as a result of the plate tectonics movements.
Answer:
18
Explanation:
The n - level given is 3
To find the number electrons that can occupy this level, we use:
2n²
n - is the energy level.
The energy level here is 3;
2 x 3² = 18
