Answer
The electron represents about $0.05445\%$ of the mass of a hydrogen atom.
Work Step by Step
We can calculate this percentage using the following formula:
$\text{Percentage of mass of electron} = \left( \frac{\text{Mass of electron}}{\text{Mass of hydrogen atom}} \right) \times 100$
Using the values: • Mass of electron ≈ 0.0005486 amu • Mass of hydrogen atom ≈ 1.007825 amu $\text{Percentage of mass of electron} = \left( \frac{0.0005486}{1.007825} \right) \times 100$
Let’s calculate that:
$\text{Percentage of mass of electron} = 0.05445\%$
So, the electron represents approximately $0.05445\%$ of the total mass of a hydrogen atom.
