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.
