1% m/v solutions are sometimes thought of as being gram/100 mL but this detracts from the fact that % m/v is g/mL; 1 g of water has a volume of approximately 1 mL (at standard temperature and pressure) and the mass concentration is said to be 100%. To make 10 mL of an aqueous 1% cholate solution, 0.1 grams of cholate are dissolved in 10 mL of ...
In Canada, a teaspoon is historically 1 ⁄ 6 imperial fluid ounce (4.74 mL) and a tablespoon is 1 ⁄ 2 imperial fl oz (14.21 mL). In both Britain and Canada, cooking utensils commonly come in 5 mL for teaspoons and 15 mL for tablespoons, hence why it is labelled as that on the chart. The volume measures here are for comparison only.
That meant that the Reputed measures varied depending on which standard gallon was used. A Reputed Pint of beer was equal to 285 mL (1/2 an Ale Pint, or equivalent to 10 imperial oz. or 9.63 US oz.) and a Reputed Quart of wine was equal to 730 mL (3/4 of a Wine Quart, or equivalent to 25.69 Imp. oz. or 24.68 US fluid oz.).
United States standard drinks of beer, malt liquor, wine, and spirits compared. Each contains about 14 grams or 17.7 ml of ethanol. A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol.
For example, to make 100 mL of 50% alc/vol ethanol solution, water would be added to 50 mL of ethanol to make up exactly 100 mL. Whereas to make a 50% v/v ethanol solution, 50 mL of ethanol and 50 mL of water could be mixed but the resulting volume of solution will measure less than 100 mL due to the change of volume on mixing, and will contain ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
A solution with 1 g of solute dissolved in a final volume of 100 mL of solution would be labeled as "1%" or "1% m/v" (mass/volume). This is incorrect because the unit "%" can only be used for dimensionless quantities. Instead, the concentration should simply be given in units of g/mL.
The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equate 1 kilogram of water with 1 L of water.
