Oxygen - Royal Society of Chemistry

Oxygen accounts for about 23% of the atmosphere's mass with pairs of oxygen atoms stuck together to make dioxygen molecules, but it's not just in the air, we breathe. Overall, it's the most abundant element on the earth's surface and the third most abundant in the universe after hydrogen and helium.

Typically, the space between molecules in the gas phase is large compared with the size of the molecules. Consider a sample of gas inside a piston cylinder (a cylinder with one movable end cap so the volume inside the piston can be changed). The gas evenly fills the volume of the cylinder (the defining property of gases).

Gas Laws - Purdue University

Practice Problem 3: Calculate the pressure in atmospheres in a motorcycle engine at the end of the compression stroke. Assume that at the start of the stroke, the pressure of the mixture of gasoline and air in the cylinder is 745.8 mm Hg and the volume of each cylinder is 246.8 mL.

Measurements | Chemistry

The density of a substance is the ratio of the mass of a sample of the substance to its volume. The SI unit for density is the kilogram per cubic meter (kg/m 3 ). For many situations, however, this as an inconvenient unit, and we often use grams per cubic centimeter (g/cm 3 ) for the densities of solids and liquids, and grams per liter (g/L ...

Isotope Ratio Mass Spectrometry - an overview ...

Isotope ratio mass spectrometry (IRMS) allows the accurate measurement of small differences in the abundances of isotopes such as 2 H/ 1 H, 13 C/ 12 C, 15 N/ 14 N, and 18 O/ 16 O. Samples are converted in gases such as H 2, CO 2, N 2, and CO depending on their chemical composition through interaction with the electron beam in the ion source.

Air-fuel ratio, lambda and engine performance – x-engineer.org

How stoichiometric air-fuel ratio is calculated. In order to understand how the stoichiometric air-fuel ratio is calculated, we need to look at the combustion process of the fuel. Combustion is basically a chemical reaction (called oxidation) in which a fuel is mixed with oxigen and produces carbon dioxide (CO 2), water (H 2 O) and energy (heat). Take into account that, in order for the ...

Empirical Formula - Purdue University

There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios. (3.336 mol O/ 3.336) = 1 mol O (4.028 mol C/ 3.336) = 1.2 mol C (8.056 mol H/ 3.336) = 2.4 mol H. Use the mole ratio to write the empirical formula. The mole ratio did not turn out to be whole numbers.
