Mole sauce Mole (/ˈmoʊleɪ/, /ˈmoʊli/ Spanish pronunciation: [ˈmole]; from Nahuatl mōlli, sauce) is the generic name for a number of sauces originally used in Mexican cuisine, as well as for dishes based on these sauces. Outside Mexico, it often refers specifically to mole poblano. In contemporary Mexico, the term is used for a number of sauces, some quite dissimilar, including black, red, yellow, Colorado (another name for red), green, almendrado, de olla, huaxmole and pipián.

Definition of Terms If the mass of a single 12 C atom is 12.000 amu, then one mole of these atoms would have a mass of 12.000 grams. By definition, a a mole of any substance contains the same number of elementary particles as there are atoms in exactly 12 grams of the C isotope of carbon.

Questions and Answers A mole is a convenient counting unit whenever one is dealing with numbers of atoms or molecules. It is equal to Avogadro's number (NA), namely 6.022 x10 23. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams. Since we only have 0.001 grams, that means that we have NA * (0.001/18) = 3.35*10 19 molecules of water!

- A mole is the amount of matter that has a mass in grams equal to the atomic mass in amu of the atoms. Thus, a mole of carbon has a mass of 12 grams. The number of atoms in a mole is called the Avogadro number, Nav = 6.023  1023. Note that Nav = 1 gram/1 amu. Calculating n, the number of atoms per cm3 in a piece of material of density d (g/cm3).

- A mole is defined as the number of atoms in exactly 12 grams of C (carbon twelve). The number is called Avogadro's Number. In the above definition, 12 is the mass number of carbon.So, one mole of carbon atoms has a mass of 12 grams. The relative atomic mass, which can be written as Ar or RAM, is the number just above the element in the periodic table (have a look, and check that carbon is 12). mole is defined as the number of atoms in exactly 12 grams of C (carbon twelve). The number is called Avogadro's Number. In the above definition, 12 is the mass number of carbon.

Juvenile Crime--Part I A second reason crime is underreported is that when several crimes are committed by an offender at the same time, only one (usually the most severe) is counted in the data. For example, if a juvenile offender robbed a store, assaulted a clerk, and killed a customer, only the homicide would be reported.

- A mole is a chemical counting unit, such that 1 mole = 6.022 * 10^23 particles. Stoichiometry also requires the use of balanced equations. From the balanced equation we can get the mole ratio. The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced equation.

The mole (mol) The mole (mol) The mole is a base unit of the International System of Units (SI). A mole is the amount of substance containing as many elementary entities as there are atoms in exactly 0.012 kilogram (or 12 grams) of carbon-12, where the carbon-12 atoms are unbound, at rest and in their ground state.

- Current usage tends to apply the term mole to an amount containing Avogadro's number of whatever units are being considered. Thus, it is possible to have a mole of atoms, ions, radicals, electrons, or quanta. This usage makes unnecessary such terms as gram-atom, gram-formula weight, etc.

Units and dimensions in chemistry Of special interest to Chemistry is the mole, the base unit for expressing the quantity of matter. Although the number is not explicitly mentioned in the official definition, chemists define the mole as Avogadro’s number (approximately 6.021023) of anything.

- It would contain a fixed number of atoms (now called a mole of atoms). If they then measured out 16 g of O atoms, which have a mass ¹⁶/₁₂ times that of a carbon-12 atom, they knew that they had the same number of atoms (a mole of each). So a mole is simply a way of counting atoms and molecules.

Definition of Terms A mole of C 12 H 22 O 11 would have a mass of 342.299 grams.This quantity is known as the molar mass, a term that is often used in place of the terms atomic weight or molecular weight. The Mole. The term mole literally means a small mass. It is used as the bridge between chemistry on the atomic and macroscopic scale. If the mass of a single 12 C atom is 12.000 amu, then one mole of these atoms would have a mass of 12.000 grams. By definition, a a mole of any substance contains the same number of elementary particles as there are atoms in exactly 12 grams of the C isotope of carbon.

mole Part of the IT standards and organizations glossary: The mole (abbreviation, mol) is the Standard International (SI) unit of material quantity. One mole is the number of atom s in precisely 12 thousandths of a kilogram (0.012 kg) of C-12, the most common naturally-occurring isotope of the element carbon. This number is equal to approximately 6.022169 x 10 23, and is also called the Avogadro constant. 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).

Moles Moles are growths on the skin. They happen when pigment cells in the skin, called melanocytes, grow in clusters. Moles are very common. Most people have between 10 and 40 moles. A person may develop new moles from time to time, usually until about age 40. In older people, they tend to fade away. Moles are usually pink, tan or brown.
