Question

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

Answer 1

Answer:

Since, we know that carbon is a chemical element which is denoted by the symbol C and also having the atomic number as 6. So, 12 grams of the pure carbon-12 will be called as one mole of the carbon. While the number of carbon-12 atoms present in the one mole of the given sample is - 6.022 x 10^23.

Again, 12g of carbon we know it is the total weight of the carbon as gram atomic mass but the 12u carbon is the relative mass 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 where we know that the u given with 12 is the atomic weight of 1 u = 1.66×10⁻²⁴g.

Answer 2

Answer:

12 g of carbon is the molar mass of carbon while 12 u of carbon is the mass of one carbon atom.
