The molar mass of NaOH is 40.0 g. What is the molarity of a solution containing 20 grams of NaOH in 500 milliliters of solution? What is the molar mass of calcium hydroxide? Given that the atomic mass is 22.99
Molecular weight is a synonym for molar mass. It is the mass of a substance per one mole of substance. The units for molecular weight are g/mol. It is used to convert between grams and moles.Answer and Explanation: The molecular weight of butane is 58.12 g/mol. The formula for ...

and mass are measured as shown below in Table 2. Tensile strength and elongation at break for each specimen is determined according to ASTM D1708. The percent mass change is calculated as the absolute value of the difference between the initial mass and the mass after immersion in water divide...
A mixing system provides for continuous mixing of the ingredients at high shear to form a substantially homogeneous liquid or semi-solid mixture in which the ingredients are distributed throughout its mass. The mixing system includes means for mixing the ingredients to provide shear effective for mai...
The hydroxylated hydrogenated polybutadiene for use in accordance with the invention has a number-average molar mass Mn of 4.000 to 6.000 g/mol, preferably 4.500 to 5.000 g/mol. Because of their high molar mass, the hydroxylated hydrogenated polybutadienes can also be referred to as macroalcohol...
