Exercise C Calculating volumelvolume % Concentration (1 pt per answer, 10 total) Complete the following table by calculating the volume/volume % for the following solutions. The volume/volume % is the volume of the solute in mL divided by the volume of the solution in mL x 100. The volume of the solution is equal to the volume solvent plus the volume of solute. Fill in all of the empty spaces. The volume of the solute and the solvent must be...

SUTULIUTIS Exercise D Calculating Molarity Concentration (1 pt per answer, 10 total) Complete the following table by calculating the molarity for the following solutions. The molarity is the number of moles of the solute divided by the volume of the solution in Liters. Use the molecular mass of the solute to calculate the moles if you only have the mass of the solute. Fill in all of the empty columns. The volume must be in Liters. Mass of solute Moles...

In this lab we will be expressing rate as a change in
concentration of reactants over time. In order to calculate this,
we need to know the initial concentrations of our reagents after
they are combined but before the reaction occurs. This is a
dilution process. Recall that the calculation for a dilution is
accomplished using the relationship M1V1 = M2V2.
If the [S2O3 2- ] is initially 2.49x10-4 M, and the reaction
takes 145 seconds for the solution to...

Dilution is a process in which the concentration of a solution is lowered by adding more solvent. Some of the reasons dilutions are performed are to minimize measurement errors when preparing a series of solutions at different concentrations, to save time and laboratory space, and to make more accurate measurements on an analytical balance when the target concentration is very low. The new concentration of a diluted solution can be determined from the following equation, sometimes called the dilution equation,...

m e usually performed, e.g., 10°>10% 10% 10%, etc. Two-fold or other dilution schemes can be applied as well. For accurate quantitation, it is important to use the selected dilution scheme consistently. correction factor is 10 (0.1 ml X 10-10 ml). If you plated 0.5 ml, the correction factor is 2. 1.-CFU/Dr Initial concentration, (lc) equals colony forming units (cfu) divided by dilution factor (Df). Note that each step of the dilution procedure reduces the...
