The Mole Concept

For centuries and decades, t’was something they needed,

Until Ostwald in 1896 to those heated discussions heeded,

Waiting for the right time, he was truly an opportunist,

And brought out a mole, the chemist’s counting unit.

People posed queries - “What’s this ‘mole’?”, “What does it do”?

What’re masses and who’s Avogadro too?

People questioned grave and long. Probing and deep

Ostwald though still called a mole ‘enough to report the atoms in a heap’

He refuted, “Convenience for scientists and mol. as an SI”,

Would not only strengthen foundations, but allow one to calculate numbers quite high.

But be wary, don’t engage in deep roles of slumber.

For, to calculate this, you need the Avogadro’s number.

From molecules or particles to moles to grams,

You can calculate it all within a second’s span

All you would need is the formula and the number

Using the mole concept, leaving others gawking, in wonder.
