Question

B. Point out the difference between 12 g of
carbon and 12 u of carbon​

Answer 1

Answer:

&

Explanation:

12 gram of carbon (which equals to one mole of carbon) is the actual mass of 6.023 × 10^23 atoms of carbon.

While amu is the unit of relative atomic mass and 1 amu equals to 1/12 of the mass of an atom of carbon-12 (which is the most common isotope of Carbon)

The mass of one atom carbon is considered as equal to 12 amu while that of hydrogen is about 1 amu.

IT SHOULD BE NOTED THAT masses of atoms are measured in amu's because an atom is so small that it is impossible to measure it physically in grams.

1 amu equals to 1/6.023 × 10 (raise to power 23) grams of Carbon-12.

Thus the net conclusion is that 12 gram is the mass of one mole (or 6.023×10^23) atoms of carbon WHILE 12 u is the mass of one atom of carbon.

HOPE IT'S CLEAR!
