The atomic mass of an element is numerically equal to the mass of 1 mole of its atoms.
1 mole of atoms = 6.022 × 1023 atoms
Now, 1 atom of element X has mass = 2.65 × 10-23g
So 6.022 × 1023 atoms of element X have mass = 2.65 × 10-23×6.022 × 1023
= 15.96 = 16g
Atomic mass of the element X is 16u.
Oxygen is the element with atomic mass 16 and having symbol O.
1 mole of atoms = 6.022 × 1023 atoms
Now, 1 atom of element X has mass = 2.65 × 10-23g
So 6.022 × 1023 atoms of element X have mass = 2.65 × 10-23×6.022 × 1023
= 15.96 = 16g
Atomic mass of the element X is 16u.
Oxygen is the element with atomic mass 16 and having symbol O.
