how many atoms are in 2.5 moles of carbon.
Answers
Answer:
4.52*10^23 atoms in 2.5 moles of carbon.
Explanation:
multiply 2.50 mol CO2 by 3 atoms/1 mol CO2 before multiplying by 6.022*10^23 atoms/1mol atoms.
In 2.5 moles of Carbon (C) there are 12.53^23 atoms. This is arrived at by utilizing Avogadro's number.
What is a mole?Mole is short for molecules. Molecules are a combination of atoms.
What is the calculation for the solution above?To derive the number of atoms in 2.5 molecules of carbon, we need to divide it's weight in grams with the atom mass units.
To get the atomic mass units (amu) we need to check the periodic table.
Once the division is done, the result must be multiplied by Avogadro's number which is stated as 6.02 x 10^23.
Thus, the formula is given as:
amu = grams/mole; or
u = g/mole
Since the Molar Mass of Carbon is 12.01g/mol
The number of atoms will be
2.5/12.01 X 6.02 x 10^23.
= 0.20815986677768526228143213988343 x 6.02 x 10^23.
= 1.2531223980016652789342214820983 x 10^23.
= 12.531223980016652789342214820983^23.
≈ 12.53^23.
It is to be noted that the molar mass of carbon is derived from the Periodic Table.

If an S wave were to go from a solid to a liquid - what would happen to its velocity?
Answers
If the S wave travels after traveling through the solid object then its speed tend to slow down after it reaches the liquid objects. As the S wave is a secondary wave and is known to have to take a different path when it reaches the liquid region.
Hence the S waves don't flow easily through this layer. Thus they are unable to travel through.Learn more about the from a solid to a liquid - what would.

Distinctions between environmental possibilism, environmental determinism and environmental probabilism
Answers
Answer and Explanation:
Environmental possibility is a thought that states that nature provides a means of modifying the human race, but it is not the main factor in the evolution of society, being a mere supplier of resources. In this teaching, the human being is the main causative agent of evolution.
Geographical determinism is thought where nature is placed as the main modifying agent of society. This is because it is nature that promotes physical and psychic changes in human beings.
Environmental probabilism is the thought that allows human beings, to see the environment as the place that presents probabilities of occurrences of various events, which can be determined through the observation of environmental characteristics.
