- From Yahoo Answers. Question: The mole concept is important in chemistry because 1. atoms and molecules are very small and themole concept allows us to count atoms and molecules by weighing macroscopic amounts of material. 2. it establishes a standard for reaction stoi-chiometry. 3. it explains the properties of gases.

- What is a Mole? 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 1023). This involves the acceptance of two dictates -- the scale of atomic masses and the magnitude of the gram. Both have been established by international agreement.

Mole-to-Mole Ratios and Calculations of a Chemical Equation Conveniently, one mole of a substance has a mass that is equal to its atomic mass expressed in grams. This relationship is known as molar mass. For example, one atom of carbon has a mass of 12.011 amu, one mole of carbon has a mass of 12.011 grams.

- The usual unit is a mole. A mole is 6.02 x 10 23 of what ever object we’re counting, atoms, molecules, or even lemmings. The number of objects in a mole is called Avogadro’s number (not avocado’s number, 6.023 x 10 23 avocados, called a guacamole; or abogado’s number which is $300/hour). So just remember that a mole is a fixed number of objects, like a dozen, a pair, a gross or a baker’s dozen. This means that when we look at a balanced equation, we can either interpret it as the number of atoms and molecules consumed and produced, or the number of MOLES of atoms and molecules consumed and produced.

The Importance of Homeostasis The Importance of Homeostasis. Among the most important features of the human body that we must be aware of is homeostasis. Homeostasis is not a collection of organs, but a synthesis of bodily functions that collectively keeps the entire body stable. In order to keep homeostasis at optimum it must have access to adequate supply of energy. Our body’s energy comes from the sun.

- A neutral atom has the same number of electrons and protons, Z. 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, N av = 6.023 10 23. Note that N av = 1 gram/1 amu.

- The study found people with more than 100 moles tended to have longer telomeres. They concluded that telomeres allow the pigmented cells that form moles to keep dividing for longer, hence, people with lots of moles may have the benefit of delayed cellular aging.

- 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.

Why Is Meiosis Important? Meiosis is important because it reprograms the gametes, which help the fertilized egg develop and grow. During the process, it maintains the integrity of the germ line by removing faulty RNA and protein, and it eliminates the defective meiocytes.

ANIMALS WE CONTROL A. Moles are insectivores, similar to bats. A mole eats 70-80% of its weight in insects every day. This is because they burn so much energy digging. In addition to consuming pest insects, they aerate the soil as they tunnel. Pretty cool, as long as they aren't in your yard.

Amount of Substance To recap, by definition a mole of any pure substance has a mass in grams equal to that of the substance's molecular mass. For example, oxygen has a molar mass or atomic weight of 16g, so 1 mole of oxygen is 16g. In contrast, gold has a molar mass of 197g, so 1 mole of gold is 197g. But, and this is the essential part, one mole of either pure oxygen or pure gold still contains the same number of atoms, i.e. 6.022 x 1023.

- Answer. Brian, I can't give you an exact answer because it depends on a lot of factors such as temperature, humidity, stage in the life cycle and so forth. However, bed bugs can live a long time as insects go and can remain dormant without feeding for long periods, probably weeks to months. can't give you an exact answer because it depends on a lot of factors such as temperature, humidity, stage in the life cycle and so forth.

Molar Mass Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA. Avogadro's number is a similar concept to that of a dozen or a gross. A dozen molecules is 12 molecules.

How Much Water Is a Mole of Water? A mole is a unit of measuring the quantity of anything. A single mole is set to the number of particles found in 12.000 grams of carbon-12. This number is 6.022 x 1023 carbon atoms. The number 6.022 x 1023 is known as Avogadro's Number. A mole of carbon-12 atoms has 6.022 x 1023 carbon-12 atoms.

- Key Points. 1  Mole fraction describes the number of molecules (or moles) of one component divided by total the number of molecules (or moles) in the mixture. 2  Mole fraction is useful when two reactive components are mixed together, as the ratio of the two components is known if the mole fraction of each is known.
