molecular weight The sum of the atomic weights of the atoms contained in a molecule. For example, since the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16, the molecular weight of water (H2O) is 1 + 1 + 16, or 18. ...
Molecular Weight Calculate melting point of hydrocarbons from molecular weight (molar mass). Hydrocarbons - Vapor Pressures Vapor pressure vs. temperature for propane, n-butane, n-heptane and n-pentane hydrocarbons. Hydrogen - Thermophysical Properties Chemical, Physical and Thermal Properties of ...

At constant Al level, polymer molecular weight (MW) increases with the Cl/alkyl ratio in the aluminum alkyl chloride.80,102,104The effect of the concentration of Al seems to depend on the type of aluminum compound used. With AlEt2Cl as cocatalyst the concentration of Al has no significant ...
The accessibility of low-molecular-weight crystallins to ammonia and hydrogen chloride vapor was obtained by high vacuum vapor sorption. The sorption and desorption isotherms were analysed regarding the gas uptake at different vapor pressures. The amount of ammonia and hydrogen chloride irreversibly ...
Hyaluronic acid (HA) is applied in a number of medical applications and HA of different molecular weight (Mw) are used in different pharmaceutical preparations. In determination of Mw by muti-angle laser light-scattering (MALS), refractive index incremen
The synthesis, molecular structure and chemical behavior of two chloride-dimethyl sulfoxide-ruthenium (III) derivatives, namely [(DMSO) 2 H][trans-Ru(DMSO) 2 Cl 4 ] (1) and mer-Ru(DMSO) 3 Cl 3 (2), are reported. They represent the first examples of fully characterized halogen-dimethyl...
2. Specific gravity method. This method calculates the molecular weight by measuring the specific gravity of a Sodium carbonate solution. In the experiment, the solution is placed in a specific gravity bottle, and the mass and volume of the solution inside the bottle are measured. Then, the mo...
Explain why hydrogen fluoride (HF) has a higher boiling temperature than hydrogen chloride(HCL)(19.4 Deg C vs. -85 Deg C), even though HF has a lower molecular weight. a) The intermolecular bonding fo Why do we use freezing...
