Question

The mass of 1 atom of element x is 2*10^minus 23gram . Calculate the atomic mass of the element x . What may be the element x?

Answer 1

mass of one atom = 2 × 10^-23 g.

mass of 1 mole i.e. 6.022 x 10^23 atoms = (2 × 10^-23) × (6.022 x 10^23)

= 12.044 g

So, atomic mass is 12.

Element is Carbon.

Answer 2

Answer:

Explanation:

Mass of 1 atom is 2*10^minus 23 gram

now 1 mole contains 6.023 * 10^23 atoms

so mass of the element is mass of atom * number of atoms

= (2 * 10^-23) * (6.023 * 10^23)

= 12.044

= 12 u

therefore atomic mass is 12 u

We know that carbon has a mass of 12 u

so it is carbon.

Hope it helps.
