Question

what will be the mass of one atom of C12 in grams​

Answer 1

Answer:

Mass of one mole of C12 = 12 g. somass of 1 atom of C12 = 1.9927e-23 g. Now coming to part where you multiplied 12 amu to 1.66e-24 g. Carbon have 12 intra nuclear particles (i.e 6 protons and 6 neutrons), each having avg mass of 1 amu which is equivalent to 1.66e-24 g.

Answer 2

1.99 x 10^-23 Grams

Given:

The mass of 1 mole of carbon atom = 12 grams

Avogadro's constant

= 6.022 x 10^23 atoms

Mass of atoms of carbon = 12 grams

To Find:

Mass of one atom of C12 in grams

Calculating:

To find the mass of Carbon atom we use the formula:

Mass of Carbon / Avogadro's Constant

Substituting the values into the formula mentioned above we get:

= 12 / 6.022 x 10^23

= 1.99 x 10^-23 Grams

Therefore, the mass of one atom of C12 atom in Grams is 1.99 x 10^-23 Grams.
