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 ...
Molarity is the concept that is used to express the concentration of the solution. The value of molarity depends upon the mass of the substance and the volume of solution taken.Answer and Explanation: Given: Molecular ...
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...
A study was made of the regulation of the molecular weight of ethylene-propylene copolymers with the catalytic system vanadium triacetylacetonate-diisobutylaluminium chloride in liquid propylene solution. The viscosity of the copolymer is reduced as the partial pressure of the hydrogen rises. An ...
21. Sulfadiazine, a sulfur drug used in the treatment of bacterial infections, is found on analysis: 48.0% carbon, 4.0% hydrogen, 22.4% nitrogen, 12.8% sulfur, and 12.8% oxygen. The molecular mass was found to be 250 amu. Calculate the molecular ...
