Question

The mass of a single atom of an element x is 2.65 × 10^-23 g. What could be this element? (hint : calculate atomic mass by finding mass of avogadro number of molecules.)

Answer 1

Step-by-step explanation:

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
