WebWeight/Volume percentage concentration (w/v%), or mass/volume percentage concentration (m/v%), is a measure of the concentration of a solution. w/v% or m/v% is calculated by dividing the mass of the solute in grams by the volume of solution in millilitres then multiplying this by 100 as shown below. w/v (%) =. mass of solute (g) WebT we have two parts to this problem. A. We need to find the p h of this buffer solution and for B, we need to know how many grams of K o. H must be added to 0.5 leaders of the buffer to change the pH by 0.15 years. So in this problem we are given this information we will first need to solve for part A. We can first find the rules of HCL 204 no ... WebThe weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.
