What is the empirical formula of lead?
PbO2
This experiment successfully identified the unknown lead oxide as lead(IV) oxide (with an empirical formula of PbO2), with an average percent error of 0.2 \%.
How is empirical formula calculated?
In summary, empirical formulas are derived from experimentally measured element masses by: Deriving the number of moles of each element from its mass. Dividing each element’s molar amount by the smallest molar amount to yield subscripts for a tentative empirical formula.

Is lead an oxide?
lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO2, in which lead is in the +4 state; and trilead tetroxide, Pb3O4. Lead monoxide exists in two modifications, litharge and massicot. Litharge, or alpha lead monoxide, is a red or reddish…
How do you find empirical formula from mass?
Convert the mass of each element to moles of each element using the atomic masses. Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles. Use the mole ratio to write the empirical formula.
What is the empirical formula mass?
1) The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. The molecular mass (formula mass, formula weight or molecular weight) of a compound is a multiple of the empirical formula mass.
