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.

In North Florida, there are concerns that groundwater withdrawals to meet regional water use demands are negatively affecting the volume of water available for natural spring systems, considered a unique and significant regional environmental resource. This complex situation creates a significant ethical dilemma. Common ethical theories were discussed in the textbook readings and outlined in the lectures. Select the pair of theories that would best apply to this ethical dilemma:
Utilitarianism approach and common good approach
Utilitarianism approach and rights approach
Fairness/justice approach and virtue approach
Rights approach and virtue approach
The correct answer is the Utilitarism approach and common good approach
Explanation:
Both utilitarianism and the common good approach focus on the ethical aspects of actions. In the case of the first approach, this emphasizes the consequences of an action by analyzing the benefits or harm related to this. This approach is effective in this ethical dilemma because it is necessary to consider both the benefits for humans that will obtain fresh water and the harm in the natural ecosystem.
On the other hand, the common good approach states any individual good including access to water is linked to the general good. In the ethical dilemma presented this implies the use of water for human society is not ethical except if it leads to a general good, which includes access to water for other species living in natural ecosystems. According to this, these two approaches or theories are the most appropriate for this dilemma.
