Amadeo AvogadroSong by Michael Offutt

Amedeo Avogadro lived in Italy,

And his work means an awful lot to chemistry.

Amedeo Avogadro may be dead—but,

We all should remember what he said.

Equal volumes of gases,At the same temp and pressure,Have the same number of molecules,Amedeo. . .Avogadro, that’s his hypothesis.

You got two balloons filled with different gases,

Equal volumes but they both have different masses.

If conditions are the same everywhere,

Tell me how the number of molecules compare.

Equal volumes of gases,At the same temp and pressure,Have the same number of molecules,Amedeo. . .Avogadro, that’s his hypothesis.

Why is his hypothesis so great?

You can use it to find atomic weights.

It’s based on the ratio of the massed,

Of equal volume of those gases.

Equal volumes of gases,At the same temp and pressure,Have the same number of molecules,Amedeo. . .Avogadro, that’s his hypothesis.

Avogadro helped shape atomic theory

But when I think about it I get sorta dizzy,

‘Cause no one believed in what he said,

Till four years after when he was dead.

Equal volumes of gases,At the same temp and pressure,Have the same number of molecules,Amedeo. . .Avogadro, that’s his hypothesis.
