The percent by mass of Lead in Lead (IV) oxide (
) is equal to 86.62%.
<u>Scientific data:</u>
- Molar mass of Lead = 207.2 g/mol.
- Molar mass of oxygen = 16 g/mol.
To calculate the percent by mass of Lead in Lead (IV) oxide (
):
First of all, we would calculate the molar mass of Lead (IV) oxide (
);

Lead (IV) oxide (
) = 239.2 g/mol.
<h3>How to calculate percent by mass.</h3>
For the percent by mass of Lead, we would calculate it by using this formula:

Substituting the parameters into the formula, we have;

Percent mass of Lead = 86.62%
