The world's longest ongoing war. For more than 60 years, Karen rebels have been fighting a civil war against the government of Myanmar. In February 1949, members of the Karen ethnic minority launched an armed insurrection against Myanmar's central government.
In Chemistry the quantities of a dozen, a century, a gross, ream and millennium are far too small. Even a million is too small. One million atoms of iron weighs 0.0000000000000000928 grams! Chemistâs measure atomic particles using a large QUANTITY called the mole. One mole is equal to 602214179000000000000000 or 6.022 x 1023 particles.
The mole is the only fundamental SI unit that is dimensionless. That means it represents a simple numerical quantity or value; it is a term similar in nature to dozen (meaning 12) or gross (meaning 144). But 1 mol is, unlike a dozen or a gross, an incomprehensibly large number.
