So, you'll want to plug the absorbance value for each unknown into the equation in place of y, then calculate x. You can use the spreadsheet program to do this calculation for you and make it quicker. You have
When conducting a scientific experiment it is necessary to know that you have the correct concentration of the different chemicals involved. It is also important to be able to calculate concentration in order to determine how much of a reactant has been used up in a reaction or how much produ...
How to Calculate Molality of a Solution Molalityis used to express the concentration of a solution when you are performing experiments that involve temperature changes or are working with colligative properties. Note that with aqueous solutions at room temperature, the density of water is approximately...
Step 3:Subtract the smaller number of moles from the larger number. Step 4:Divide the number of moles by the total amount of volume used to get the concentration. Step 5:Plug the concentration value into the correct formula and use it to calculate pH. ...
To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and the conjugate base's is on the bottom. What is the pH of a buffer? The pH of a solution, buffer or ...
