if one mole of carbon atoms weighs 12g what is the mass of 1 atom of carbon?? plss explain....
Molar mass is the mass of one mole of the substance, and we know that one mole of a substance consists of 6.022 X 1023 particles of the substance. Thus, if the molar mass of carbon is 12g, it means it is the mass of 6.022 X 1023 atoms of carbon. So
mass of 6.022 X 1023 atoms of carbon = 12g
mass of 1 atom of carbon = 12 / (6.022 X 1023)g = 1.993 X 10-23 g
