Calculate the concentration of a weak base (or its conjugate acid), given its pH, pKb and the concentration of the weak acid (or its conjugate base). Determine the concentration of ammonia in an ammonia buffer with pH of 10.1 and ammonium ion concentration of .98 M, keeping in mind that...
How to Calculate Kcat In chemical reactions catalyzed by an enzyme, the enzyme lowers the amount ofactivation energyrequired by temporarily bonding with the substrate and twisting it into a strained state. The k(catalyst) or "kcat" for the reaction refers to the concentration-independent constant ...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
How to Find Molarity As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to con...
To calculate molarity: Find the number of moles of solute dissolved in solution, Find the volume ofsolutionin liters, and Divide moles solute by liters solution. Make certain to use the correct number of significant figures when reporting your answer. One easy way to track the number of sign...
