Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid is 1.05 times that of water, it has a specific gravity of 1.05. In UK brewing usage, it is customary to regard the reference value for water to be 1000, so the specific gravity of the same example beer would be quoted as 1050.
In Canada, liter size bottles are only found at Duty Free stores. Third (US) 42 US fl. oz. 43.71 Imp oz. 1.24 L: A third (1 ⁄ 3, or 0.333) of a US gallon, rounded down from 42.66 US fl. oz. It was used for cheap liquor like gin and malt liquor. Later rounded down to 40 US fl. oz. (41.63 imp. oz. [1.18 L]) in the 1960s. Half gallon (US) 64 US ...
[31] [32] There are on the order of 10 32 molecules of water in an Olympic-size swimming pool and if such a pool were filled entirely with a 15C homeopathic preparation, to have a 63% chance of consuming at least one molecule of the original substance, one would need to swallow 1% of the volume of such a pool, or roughly 25 metric tonnes of water.
For example, the conversion factor between a mass fraction of 1 ppb and a mole fraction of 1 ppb is about 4.7 for the greenhouse gas CFC-11 in air (Molar mass of CFC-11 / Mean molar mass of air = 137.368 / 28.97 = 4.74). For volume fraction, the suffix "V" or "v" is sometimes appended to the parts-per notation (e.g. ppmV, ppbv, pptv).
where TDS is expressed in mg/L and EC is the electrical conductivity in microsiemens per centimeter at 25 °C. The conversion factor k e varies between 0.55 and 0.8. [5] Some TDS meters use an electrical conductivity measurement to the ppm using the above formula. Regarding units, 1 ppm indicates 1 mg of dissolved solids per 1,000 g of water. [6]
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [2]
Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of ...
It contains 1% sodium hypochlorite (NaClO) and 16.5% sodium chloride (NaCl; common salt). 1:80 dilution is used to sterilise babies' feeding utensils, including baby bottles. It is sold in dissolvable tablets which are then mixed with cold water and placed in a lidded bucket. This method of bottle sterilization is marketed as "The Milton Method".
