Question

What is the value that corresponds to the number of atom

in12.01g of carbon, that is 6.02 times 10exponent23
individualparticles?

Answer 1

6.022 x 10²³

Step-by-step 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.
