Looking for online definition of MM or what MM stands for? Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. These traditional units are often denoted by a capital letter M (pronounced "molar"), sometimes preceded by an SI prefix, as in: mol/m 3 = 10-3 mol/dm 3 = 10-3 mol/L = 10-3 M = 1 mM . 13.8 The partial pressure of O2 in your lungs varies from 25 mm Hg to 40 mm Hg. What does the letters MM mean in roman numerals? Chemistry MM abbreviation meaning defined here. Members. What is the Difference Between Molarity and Molality? Daten über Ihr Gerät und Ihre Internetverbindung, darunter Ihre IP-Adresse, Such- und Browsingaktivität bei Ihrer Nutzung der Websites und Apps von Verizon Media. Routine pressure measurements in medicine include: In physiology manometric units are used to measure Starling forces. This brings up a common mistake people make when preparing molar solutions. More precisely the amount concentration. Want to improve this question? An actual mercury column reading may be converted to more fundamental units of pressure by multiplying the difference in height between two mercury levels by the density of mercury and the local gravitational acceleration. How can you tell if Windows XP is 64bit or 32bit if you only have the partition/filesystem on a hard drive?

Dazu gehört der Widerspruch gegen die Verarbeitung Ihrer Daten durch Partner für deren berechtigte Interessen. Although not an SI unit, the millimetre of mercury is still routinely used in medicine, meteorology, aviation, and many other scientific fields. Viewing 3 reply threads. The lowercase m indicates molality, which is calculated using moles of solute per kilograms of solvent.

Why can’t gravitons distinguish gravity and inertial acceleration? One millimetre of mercury is approximately 1 Torr, which is 1/760 of standard atmospheric pressure (101325/760 ≈ 133.322368421053 pascals).

This resulted in defining a "millimetre of mercury" as the pressure exerted at the base of a column of mercury 1 millimetre high with a precise density of 13595.1 kg/m3 when the acceleration due to gravity is exactly 9.80665 m/s2. It's important to dilute a molar solution to the correct volume rather than add a volume of solvent.

The use of an actual column of mercury to measure pressure normally requires correction for the density of mercury at the actual temperature and the sometimes marked variation of gravity with location, and may be further corrected to take account of the density of the measured air, water or other fluid.
