Calculate the moles of substance by dividing the mass of substance in grams by the molecular weight in amu. In this case, the aspirin tablet contains 250 mg, or 0.250 g. Therefore, 0.250 g ÷ 180.17 amu = 0.00139 moles of aspirin.

MOLES OF ELEMENTS IN A FORMULA compound. For example, one mole of aspirin contains 9 moles of carbon atoms, 8 moles of hydrogen atoms and 4 moles of oxygen atoms.

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

The mole is a unit used in chemistry that is equal to Avogadro’s number. It is the number of carbon atoms in 12 grams of the isotope carbon-12. The word mole comes from the word molecule.

A mole, per the dictionary, is “a large solid structure on a shore serving as a pier, breakwater, or causeway.” That’s what the British forces use to evacuate their men from the beaches of Dunkirk because the waters are too shallow to get the ships all the way to the shore.

A mole of donuts is 6.02 x 1023 donuts, and a mole of basketballs is 6.02 x 1023 basketballs—and that’s a lot of basketballs! A mole of basketballs would just about fit into a ball bag the size of the Earth!…

See gun moll. In Australia and New Zealand, usually pejorative or self-deprecating, for a woman of loose sexual morals, or a prostitute. In Western Australia, circa 1970-1990s and less commonly after, Mole can be both an insult or friendly term of endearment for women.

The difference between Mole and Snitch. When used as nouns, mole means a pigmented spot on the skin, a naevus, slightly raised, and sometimes hairy, whereas snitch means a thief. A pigmented spot on the skin, a naevus, slightly raised, and sometimes hairy.

Female agents using such tactics are known as sparrows, while male ones are known as ravens. A commonly known type of sexpionage is a honey trap operation, which is designed to compromise an opponent sexually to elicit information from that person.

MDMA, short for 3,4-methylenedioxymethamphetamine, is most commonly known as Ecstasy or Molly. It is a laboratory-made drug that produces a “high” similar to the stimulants called amphetamines.

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

Because 1 mole = 6.02 x 10 23 atoms and the molar mass of an element is equal to one mole, the mass of a single atom can be calculated by dividing the mass of one mole by Avogadro’s number.

Since a penny is composed of 97.50% zinc and 2.50% copper, it therefore contains 2.4375 grams of zinc and 0.0625 grams of copper. At a molar mass of 65.380 grams per mole for zinc and 63.546 grams per mole for copper, a penny therefore contains 0.037282 moles of zinc and 0.00098354 moles of copper.

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023.
