atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
For covalent substances, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now p...
The lungs may be separated (for the purposes of mass transfer/gas exchange) as a dead space and an alveolar space. The dead space consists of the trachea, the bronchioles, and the bronchi, which are all large segments of the airway where there is air flow but no gas exchange with the ...
This is defined as “the average mass of the molecule divided by 1/12 of the mass of an atom of the nucleide C12.” The older term molecular weight is still widely used by polymer technologists. Frequently, quoted molecular weights are dimensionless, but again can be quoted in kg mol−...
so what has more mass 1 cubic foot of dry air or moist air?surprising but understandable it is dry air... molecular weight of an air molecule is more than a water molecule...so as water displaces the air molecules in humid air its mass per unit of volume decreases..i reali...
Theory of nanomechanical spectrometry. During the steady- state motion of the cantilever, the average rates of kinetic energy and potential energy must be equal. This equality provides the resonance frequencies of the system and allows an easy under- standing of the effect of particle adsorption. ...
% lumenogenesis efficiency) (Fig.4q). This improved performance of 3D microcapsules could potentially be explained by the conformal encapsulation, which unlike microwells controls molecule transport via diffusion by locally preventing convection, therefore allowing for the more efficient buildup of an ...
The successful coupling of IR-laser ablation with metastable-induced chemical ionization resulted in an ambient plasma-based spatially resolved small molecule imaging platform for mass spectrometry (MS). The analytical capabilities of IR-LAMICI are explored by imaging pharmaceutical tablets, screening ...
2 The Atomic Basis of the Law of Multiple Proportions 3 1. All matter consists of atoms. 2. Atoms of one element cannot be converted into atoms of another element. 3. Atoms of an element are identical in mass and other properties and are different from atoms of any other element. 4. ...
1eV/molecule=1.6022×10−19×6.0221×1023=96.48 kJ mole−1=3.8268 ×10−20×6.0221×1023=23.045 kcal mole−1 Thus, the formation of deuterium from a neutron and a hydrogen atom would lead to the liberation of 214.6 × 106 kJ (51.3 × 106 kcal) for each mole...
