1. Count The Number of Each Atom The first step to finding the molar mass of Acetonitrile is to count the number of each atom present in a single molecule using the chemical formula, CH3NC: ElementNumber of Atoms C(Carbon)2 H(Hydrogen)3 ...
1. Count The Number of Each Atom The first step to finding the molar mass of Indole-3-Acetonitrile is to count the number of each atom present in a single molecule using the chemical formula, C10H8N2: ElementNumber of Atoms C(Carbon)10 ...
The reversed phase behaviour of high molecular mass polystyrenes was investigated on a C18 bonded phase column using acetonitrile as the polar mobile phase component and dichloromethane, chloroform and carbon tetrachloride, as separate nonpolar components. Solvent solubility compositions, elution compositions...
Molar Excess Gibbs Free Energy refers to the additional Gibbs free energy associated with the mixing of substances in a system, excluding the contribution from the ideal entropy of mixing and volume effects. It is a measure of the non-ideal behavior of a mixture. ...
Triethyl amine and Acetonitrile were purchased from Merck&Co (Mumbai, India). All reagents used were of HPLC grade. 2.2. Apparatus AKTA-MALS- PAT analysis was performed using AKTA PURE Separation Module (GE healthcare Life sciences, Pittsburgh, PA, USA) equipped with UV detector, further ...

(methyl methacrylate) samples with molar masses in the range between 50 000 and 20 000 000 g·mol 1 and with low polydispersities were measured by sedimentation analysis in the analytical ultracentrifuge (Beckman Model E) with UV optics ( λ = 226 nm) using acetonitrile as solvent at the ...
The VΦ°values were found to decrease systematicallywith increasing temperature and mass fraction of acetonitrile in themixed-solvent medium. The results are discussed in terms of the solvodynamicand thermodynamic interactions that prevail in the IL solutions investigated.Nandi...
Keywords: poly(phenylene methylene); tungsten(II) catalysts; high molar mass; fractionation; chain-growth polymerization; homoconjugation 1. Introduction Poly(phenylene methylene) (PPM) consists of phenylene rings bridged by a methylene unit (Figure 1a). PPM is completely amorphous [1–5] and ...
