Question

point out the different between 12 g carbon and 12 u of carbon ​

Answer 1

Explanation:

Carbon is a chemical element having the symbol C and the atomic number as 6. Exactly 12 grams of pure carbon-12 is known as one mole of carbon. The number of atoms of carbon-12 present in the one mole sample is - 6.022 136 7 x 10`23

12g of carbon is the overall weight of carbon expressed in the form of gram atomic mass, whereas, 12u of carbon is weight of carbon expressed as relative mass  or is the mass of one carbon - 12 atom, where u is the atomic mass whose actual weight is -

1 u = 1.66×10⁻²⁴g
