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.
a mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram mole is the amount of pure substance containing the same number of chemical units as there are atoms in exactly 12 grams of carbon 12 i e 6 023 x 10 23 this involves the acceptance of two dictates the scale of atomic masses and the magnitude of the gram
