Question

mass of a single atom of element x is 2.65 x 10^-23g Write down the atomic mass and name of the element.​

Answer 1

Answer:

The atomic mass of element is numerically euqal to the mass of 1 mole of its atoms. Since 1 mole of atoms is 6.022×1023 atoms, so it means that the atomic mass of an element is numerically equal to the mass of its 6.022×1023 atoms. Thus, the atomic mass of the element X is 16 u.
