Determination of the diffusion coefficient of sucrose in water and its
... Interestingly, the diffusion coefficient can be used to determine not only quantitative transport properties of a solute but also certain structural characteristics of the solute in a given solvent environment. The relationship between the diffusion coefficient and the “size” of the solute is contai ...

Stoichiometry 2
... Scientists are able to determine the mass of individual atoms and/or molecules using a mass spectrometer. The resulting mass spectrum gives a parent peak (M+), which gives (is) the formula weight (and, therefore, molecular weight) of the specie under study. Ever wondered why the masses of individual ...

Chapter 4. Aqueous Reactions and Solution Stoichiometry
... A common way to determine the concentration of a solution is via titration. We determine the concentration of one substance by allowing it to undergo a specific chemical reaction, of known stoichiometry, with another substance whose concentration is known (standard solution). • Monoprotic acids and ...

Solving Linear Systems by Graphing
... A system of linear equations is a set of two or more linear equations containing two or more variables. A solution of a system of linear equations with two variables is an ordered pair that satisfies each equation in the system. So, if an ordered pair is a solution, it will make both equations true ...
