Question

Mass of an atom of an element is 2×10 ^-23g . calculate its gram atomic mass.​

Answer 1

Answer:

Gram atomic mass is the mass of one mole of an element. It is determined by taking the atomic weight for an element on the periodic table and expressing it in grams. So, for example, sodium (Na) has an atomic weight of 22.99 u, so it has a gram atomic mass of 22.99 grams.

Explanation:

According to mole concept:

1 mole of an atom contains 6.022× 10^{23}

number of atoms.

Mass of 1 atom is given us as 2× 10^{-23}g

2×10 ^−23 × 6.022×10 ^23

= 12.044g

Hence, the atomic mass of element X is 12.044 grams.
