Answer: There are 
atoms of carbon in the given moles.
Explanation:
We are given 24.6 moles of carbon and we need to find the number of atoms.
According to mole concept:
1 mole of an element contains 
number of atoms.
So, 24.6 moles of carbon will contain 
atoms.
Hence, there are atoms of carbon in the 24.6 moles of carbon.
The molar mass of CO2 is 44 grams per mole.
165 grams / 44 grams per mole of CO2 = 3.75 moles CO2
Using Avogadro’s law where 1 mole of substance equals
6.023 x 10^23 molecules
3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2
Answer:
6.022 x 10²³
Explanation:
Data Given:
mass of carbon = 12.01 g
individual particles = 6.02 x 10²³
number of atoms = ?
Solution:
Formula used to find the number of atoms
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
So, first we have to find number of moles
Formula to find no. of moles
no. of moles = mass in grams/ molar mass. . . . . (2)
molar mass of Carbon = 12.01 g/mol
Put values in eq.2
no. of moles = 12.01 g / 12.01 g/mol
no. of moles = 1 mol
Now put the values in eq. 1
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
1 mol = number of atoms / 6.022 x 10²³
Rearrange the above equation
number of atoms = 1 mol x 6.022 x 10²³
number of atoms = 6.022 x 10²³
So it is 6.022 x 10²³ atoms in 12.01 grams of carbon. This 6.022 x 10²³ also Known as Avogadro's number that is one mole of any substance consists this number of atoms.
Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km). The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
