What is the average atomic mass of oxygen? Oxygen: Oxygen is a very important element for animals because it is required for cellular respiration. Plants generate oxygen in the chemical reaction known as photosynthesis. Oxygen is in the second row and sixteenth column on the periodic table. ...
The molar mass or atomic mass of a substance is known as the quotient of the number of grams to the total number of moles and is measured in grams per mole or AMU (atomic mass unit). The general mathematical formula for the averag...
If average atomic mass of nitrogen is 14.0067, what is the % abundabce of the two isotopes ? View Solution Boron has two stable isotopes, .10B(19%) and .11B(81%). The atomic mass that should appear for boron in the periodic table is View Solution Boron has two stable isotopes, ....
What is the average atomic mass of Mg?Atomic Mass and Mass Number:The atomic mass is a form of calculated average mass for all the atoms of an element. This differs from mass numbers in that a mass number refers to the mass of a specific atom or the atoms of an isotope of an ...
and the nitrogen flow rate was 20 ml/min. The time needed to cause degradation, TD, was measured by a thermogravimetric analyzer (TGA, Perkin Elmer 7 series) at 300°C under a gas flow rate of 20 ml/min. The TD was then taken as the time to cause a weight loss of 1.5 wt% when...
In crude helium, there are nitrogen and methane gases that must be removed. The crude helium is compressed in cryogenic separation systems, which then cool the gases to subzero temperatures before they liquefy. Once liquified, the nitrogen and methane gases are drained. Heat and oxygen are added...
What are the average translation kinetic energiesKAvgof the oxygen molecules and nitrogen molecules in the air that breathe ? Assume that air is an ideal gas at a temperature of 300 K , which is the traditional value taken for room temperature . ...
The average kinetic energy of an ideal gas at absolute temperature is given by: {eq}E = \frac{3}{2} K_B T {/eq} where, {eq}K_B {/eq} = Boltzmann constant T = Absolute temperature in kelvin The value of Boltzmann constant is {eq}1.3...
For the common isotope of nitrogen 14N, calculate: a. The mass defect. (Delta M = u) b. The binding energy. (E = MeV) c. The binding energy per nucleon (E per nucleon = MeV nucleon) The mass of a ^{238}_{92}U nucleus is 238.05 amu. If the mass o...
nitrogen gas laser. The focused line which is transverse to the beam produced by the exciting laser, and transverse to the direction of the flowing dye lies near the surface of the dye material in the cell, and is substantially as long as the cell is wide. The cell lies within an ...
