If 6.02 × 1023 atoms of nitrogen have a mass of 14.0 g, what is the atomic mass of nitrogen?
Question
If 6.02 × 10^23 atoms of nitrogen have a mass of 14.0 g, what is the atomic mass of nitrogen?
Solution
The atomic mass of an element is the mass of one atom of that element. In this case, we are given that 6.02 × 10^23 atoms of nitrogen have a mass of 14.0 g.
This number, 6.02 × 10^23, is known as Avogadro's number, and it represents the number of atoms in one mole of a substance.
So, if 6.02 × 10^23 atoms (or one mole) of nitrogen have a mass of 14.0 g, then the atomic mass of nitrogen is 14.0 g/mole.
This is because the atomic mass is defined as the mass of one mole of that element. So, the atomic mass of nitrogen is 14.0 g/mole.
