Calculate the concentration of the original protein This comes from Beer's Law: A = εcl, where A is the absorbance, ε is the extinction coefficient, c is the concentration, and l is the path length. …

Since this value represents the number of moles of phosphoric acid present in #10^3# #"mL"# of solution, you can say that its molarity is equal to #color (darkgreen) (ul (color (black) ("molarity …

May 7, 2017 · The needed volume is 0.119 L To calculate the volume we use the following formula: (mol)/(volume) =concentration We know that the final concentration should be 0.156 …

If you want to calculate mass concentration, divide the mass of the solute #m# by the volume of solution #V#.

Explanation: Solubility constant only deals with the products and it can be gotten from the concentration of the products..

The molar concentration of the ammonia is 0.015 mol/L. > Your textbook is misleading you. The 57.6 % figure is calculated as if the ammonia were in the form of "NH"_4"OH". Also, the …

6.2 * 10^(-4) The idea here is that you can find the equilibrium concentration of atomic bromine, "Br", by using the percent of molecular bromine, "Br"_2, that gets converted by the reaction. …

Calculate the decreases in concentration of "N"_2 and "H"_2 Δ ["N"_2] = "-2.5 mol" /"0.050 L "= "-50.0 mol/L" Δ ["H"_2] = "-7.5 mol" /"0.050 L "= "-150 mol/L" We can set up an ICE table as we …
