मोलेरिटी इसके अंग्रेजी अर्थ का उदाहरण

Various sorts of iodinated contrast agents exist, with variations occurring between the osmolarity, viscosity and absolute iodine content.

Non-ionic dimers are favored for their low osmolarity and toxicity, but have a correspondingly higher price attached to their use.

Osmolality and osmolarity are measures that are technically different, but functionally the same for normal use.

Whereas osmolality (with an "l") is defined as the number of osmoles (Osm) of solute per kilogram of solvent (osmol/kg or Osm/kg), osmolarity (with an "r") is defined as the number of osmoles of solute per liter (L) of solution (osmol/L or Osm/L).

Osmolality versus osmolarity.

Osmolarity is affected by changes in water content, as well as temperature and pressure.

For a given solution, osmolarity is slightly less than osmolality, because the total solvent weight (the divisor used for osmolality) excludes the weight of any solutes, whereas the total solution volume (used for osmolarity) includes solute content.

Otherwise, one litre of plasma would be equivalent to one kilogram of plasma, and plasma osmolarity and plasma osmolality would be equal.

However, at low concentrations (below about 500 mM), the mass of the solute is negligible compared to the mass of the solvent, and osmolarity and osmolality are very similar.

Therefore, bedside calculations are actually in units of osmolarity, whereas laboratory measurements will provide readings in units of osmolality.

Plasma osmolarity of some reptiles, especial those from a freshwater aquatic environment, may be lower than that of mammals (e.

Calculated osmolarity (CO).

Calculated osmolarity 2 Na + Glucose + Urea (all in mmol/L).

As Na+ is the major extracellular cation, the sum of osmolarity of all other anions can be assumed to be equal to natremia, hence [Na+]x2 ≈ [Na+] + [anions].

If the patient has ingested ethanol, the ethanol level should be included in the calculated osmolarity:.
