Question

Chemistry question class 9​

Answer 1

Mass of one mole of carbon atom = 12g

1 mole of a carbon contains 6.022 X 1023 atoms

Hence, mass of 6.022 X 1023 Atoms of carbon = 12g

Mass of 1 atom of carbon = ?

= 12/6.022 X 1023 = 1.993 X 10-23 g

Answer 2

Mass of one mole of carbon atom =12 g

A mole of carbon contains 6.022×1023 atoms

Hence, mass of 6.022×1023 atoms of carbon =12 g

Mass of 1 atom of carbon= 12/6.022×10^23=1.993×10^−23g
