Question

1 atom of an element weighs 1.792×10×23g . What is the atomic weight of element

Answer 1

Answer:

The mass of one atom of the element given is = 1.792×10^23g.

We know the 1 mole of an atom = 6.023 x 10^22 atoms.

And we also know that 1 mole of an atom is equal to its atomic mass.

Mass of one atom of the element according to the question =1.792×10^23g.

Mass of 6.023 x 1023 atoms of an element = 1.792×10^23g X 6.023 x 10^22

=107.9g is the atomic weight of element.

Answer 2

Answer: 1 mole of atoms = 6.022×10²³=GAM of element

Explanation: mass of 1 element of atom= 1.792×10²³g  (given)

we know that 1 mole of an element = 6.022×10²³ atoms

1 mole of an element = its atomic mass

A/Q

mass of 1 atom of the element =1.792×10²³g

∴ mass of 6.022×10²³×1.792×10²³=107.92g
