Question

The mass of an atom of element A is 3.33 × 10–25 kg. Find its atomic weight?

Answer 1

mass of an atom (A) = 3.33 × 10 ^ - 25 kg

since , the mass and atomic weight both are similar

so atomic weight of A is = 3.33×10 ^ -25 KG..

HOPE IT HELPS

Answer 2

The Atomic Weight Of Element A Is 20.05 grams.

GIVEN

Mass of 1 atom of element = 3.33 × 10⁻²⁵ kg

TO FIND

Atomic weight of the element

SOLUTION

We can simply the problem under,

We know that

Atomic mass = molar mass of elment

Number of atoms in 1 mole of element = 6.022×10²³

Mass of 1 atom of element = 3.33× 10⁻²⁵kg

or, = 3.33 × 10⁻²²grams

Mass of 1 mole of of atoms = 6.022× 10²² × 3.33× 10⁻²²

= 20.05 grams

Hence , the atomic weight of element A is 20.05 grams
