Figure4.14: Single extraction of hyoscyamine (K ∼ 4) ( K ∼ 4) from water into diethyl ether. In this example, a single extraction resulted in extraction of 80% 80 % of the hyoscyamine (100% × 0.40g/0.50 g) ( 100 % × 0.40 g / 0.50 g) from the aqueous layer into the organic layer. The partitioning of the compound between the two layers
Thedilution ratio is the ratio of the solute (the substance to be diluted) to the solvent (e.g., water).The diluted liquid needs to be thoroughly mixed to achieve true dilution. If you have a 1:3 dilution, i.e., a 1:3 dilution ratio, this means that you add 1 unit volume of solute (e.g., concentrate) to 3 unit volumes of the solvent (e.g., water), which will give aExample A sample of water is found to contain 2 ppm lead. This means that for every million parts, two of them are lead. So, in a one gram sample of water, two-millionths of a gram would be lead. For aqueous solutions, the density of water is assumed to be 1.00 g/ml for these units of concentration.
240mL . boiling water. salt. 40 g . freshly chopped parsley. 200 g . chopped tomato. 15 g . freshly chopped mint. 3 . spring onions, thinly sliced. 60 mL . If there is any excess water, drain130grams to water = 130 ml. 130 g water = 130 milliliters. To convert 130 gr to ml for any substance we have to know, both, the substance’s density ρ in g/cm3 or in any other unit, and the mass, which is 130 grams in the case here. You can find the density of all materials in the search engine of your preference. .
