Answer to Question #161862 in General Chemistry for Festus

Question

Calculate the number of atom in 6.0 g of carbon , C = 12.0 g

Answer 1

Mass of C= 6.0g

Molar mass of C= 12.0g

Moles of C= 6.0/12.0 = 0.50g

1mole of carbon contains 6.02 x 10²³ atoms (AVOGADRO'S number)

0.50 mole of Carbon will contain 0.50 x 6.02 x10²³/1.0

=3.01 x 10²³ atoms of Carbon
