The following table gives the osmotic pressures as a function of concentration for the polymer polyisobutylene dissolved in benzene at 298.15 K. c/(g·dm−1)Π/(Pa) 20.0 210.3 15.0 150.4 10.0 100.5 5.0 49.5Extrapolate the data to infinite dilution to obtain a value for the molecular weight...
The reaction mixture contained naphthalene and t-butanol, with benzene as the solvent. The reaction products were analyzed using gas chromatograph (Shimadzu) equipped with 2 m long 5%SE-30 column and FID. The products were confirmed by GCMS analysis. View chapterExplore book Recent Progress in ...
1. Count The Number of Each Atom The first step to finding the molar mass of Benzenesulfonic Acid is to count the number of each atom present in a single molecule using the chemical formula, SO3C6H6: ElementNumber of Atoms S(Sulphur/Sulfur)1 ...
1. Count The Number of Each Atom The first step to finding the molar mass of Tricyclobutabenzene is to count the number of each atom present in a single molecule using the chemical formula, C6H6C6H6: ElementNumber of Atoms C(Carbon)12 ...
Excess molar volumes dependence with temperature for the mixtures butyl acetate + aromatic hydrocarbons (toluene, ethylbenzene, p-xylene, mesitylene, isopropylbenzene, butylbenzene, isobutylbenzene, and t-butylbenzene) were determined from density measurements by a vibrating-tube densimeter. The excess...
amines and alcohols. Soluble in organic solvents such as; acetone, benzene, carbon tetrachloride, decalin, dimethylcarbitol, ethyl acetate, methyl isobutyl ketone and 1,2-dichloroethane. Insoluble in alcohols such as ethanol and propanol. Will slowly dissolve as esterification of the anhydride occurs....
What is the molar mass of sodium sulfate? Determine the boiling point of a solution that contains 5.00 g of biphenyl (C12H10, molar mass = 154.21 g/mol) and 7.50 g of naphthalene (C10H8, molar mass = 128.17 g/mol) dissolved in 228 mL of benzene (density = 0.877 g/mL). Pure benz...
Using the above calculator you could find that e.g. a pollution of 1 gram of benzene in a certain amount of water converts to NA/78.11≈ 7.7098 × 1021 molecules polluting that water! [ Calculators ] [ Converters ] [ Periodic Table ] Molecular weight cutoff (MWCO)...
What is the molar mass of Benzene? What is the mass, in grams, of 2.70 \times 10^{-3} mol of ammonium phosphate? Calculate the molar mass of ammonium chloride. What is the molar mass of C4H7O? What is the molar mass of Ba(OH)2? What is the molar mass of the substance with ...
A molecular weight profile of soluble polymers may be obtained by a chromatographic method known as size exclusion chromatography (SEC), which is also known as gel permeation chromatography (GPC). The chromatography column consists of a “gel” such as polystyrene cross-linked with divinyl benzene....
