Thanks for the quick reply! Yes, the procedure says to add pectinase solution to pieces of fruit and then take the volume of the filtered liquid. My problem is that, since both the juice produced from the reaction and the pectinase solution are liquid, the volume of the liquid after filtering...

Homework Statement I was looking up experiments that could help me determine the effects of different factors on enzyme activity, and I noticed that in most of the experiments that included the enzyme pectinase, pectinase was not treated as a liquid. For example, after letting pieces of fruit...

Thanks for the quick replies, everyone! What I actually meant by this problem was that the concentration of the solution has to be found, in some way, using its index of refraction. It's probably easier to do it in a different way, but in this case, the index of refraction must be used...

Homework Statement Is there any way to calculate a solution's concentration (mass percentage - that is, the percentage of the solute mass to the solution mass) just by knowing its index of refraction? If it helps, the solute is NaCl, so I know the molar mass of the solute. I also have the...

Homework Statement I'm doing an experiment for Science Fair, and one of the parts requires that I know the mass of a solute (NaCl) dissolved in a solvent (water). Is there any equation I can use to find this? I cannot use concentration, but I have the total mass of the solution, the total...
