You have a beaker containing 1 L of 1 mOsM glucose. Add or subtract the solutions or solute listed below, then determine the concentration of the mixed solution. Use the equation solute/volume = concentration (S/V = concentration) for each scenario to find the concentration of the added solution.
Remember that you cannot just add concentrations. You must first consider the sum of the solutes, then consider the total volume before expressing the value as the concentration (solute amount/total volume) of the mixed solution.
Match the solutions with the correct box to indicate whether the final concentration of the mixed solution has increased, decreased, or remained the same.
