What number of Fe atoms and what amount (moles) of Fe atoms are in 500.0 g of iron?
Interpretation Introduction
Interpretation: The amount (moles) and number of iron
Concept introduction: The atomic mass is defined as the sum of number of protons and number of neutrons.
The amount of substance containing
Hence,
Also, the formula of number of moles is,
Explanation of Solution
To determine: The number of iron
Given
The mass of iron is
The atomic mass of iron atom is
The mass of single atom (in grams) can be calculated by dividing molar mass with Avogadro’s number. Thus,
Mass of one iron atom
Hence, the number of iron
Number of iron atoms
The number of iron atom is
