15% (w/v)是什么意思?
|
|||
|
搞不明白是什么意思 (1)把15克高分子溶在85ml的溶劑中 (2)把15克高分子溶在100ml的溶劑中 (3)100ml溶液中含有15克高分子 不知道是哪種才對,如果第三種的話那配置起來不是很麻煩。 |

Mass-volume percentage,重量體積比 Mass-volume percentage,v指的是溶液終體積而不是溶劑體積 Mass-volume percentage, (sometimes referred to as weight-volume percentage or percent weight per volume and often abbreviated as % m/v or % w/v) describes the mass of the solute in g per 100 mL of the resulting solution. Mass-volume percentage is often used for solutions made from a solid solute dissolved in a liquid. For example, a 40% w/v sugar solution contains 40 g of sugar per 100 mL of resulting solution. |

3 w/v 質(zhì)量濃度 x質(zhì)量固體溶于某溶劑中,終體積y Mass concentration In chemistry, the mass concentration (or ) is defined as the mass of a constituent divided by the volume of the mixture :[1] The volume in the definition refers to the volume of the solution, not the volume of the solvent. One liter of a solution usually contains either slightly more or slightly less than 1 liter of solvent because the process of dissolution causes volume of liquid to increase or decrease. Sometimes the mass concentration is called titer. https://en.wikipedia.org/wiki/Mass_concentration_(chemistry) |
