How many moles of carbon is 5.10 * 10^25 atoms of carbon

Data Given:

no. of atoms of carbon = 5.10 x 10²⁵

no. of moles of carbon = ?

Solution:

Formula will be used

no. of moles = number of atoms / Avogadro's number

Where

Avogadro's number = 6.022 x 10²³

Put values in above formula

no. of moles = 5.10 x 10²⁵ atoms / 6.022 x 10²³ (atoms/mol)

no. of moles = 84.7 mol

no. of moles of carbon = 84.7 mol
