Calculate the molecular mass (in amu) of NI3. How do you determine the mass of a gaseous compound? What is the difference between relative atomic mass and relative molecular mass? If the molar mass of a substance is 20.0 g/mol, what is the mass of 4.01 \times 10^{23} molecules of ...
The concentration of the substance is the amount of the substance present in the total amount of solution. It can be measured in different ways such as molarity, molality, mass percent, mole fraction, etc. Answer and Explanation: Molality is defined as the number of moles of solute present...
In all of these assays, the unit of activity can be expressed as a Trolox equivalent antioxidant capacity (TEAC) or defined as the concentration (mM) of Trolox having equivalent antioxidant capacity to a 1.0 mM solution of the substance under study. TEAC values derived from different antioxidant...
