An atom of an element weighs 5.88 × 10-23 g. What is the atomic mass of this element in atomic mass units?

Solutions

Expert Solution

Given the mass of one atom is , m = 5.88x10-23 g

The mass of 6.023x1023 atoms is = M = mx6.023x1023

                                                         = 5.88x10-23 gx6.023x1023

                                                        = 35.4 g

We know that 1 mole of any substance contains avagadro number(6.023x1023) of atoms.

So the atomic mass of element is the mass of avagadro number of atoms is 35.4amu
