Question
For each of the following, identify the solute, solvent, and solution. a) 10 % by mass KNO_3(aQ) b) a glass of wine containing 12% by volume ethanol in an aqueous solution In this experiment, you will use/calculate the concentration of solutions using a variety of concentration units. Refer back to chapter 9 in your textbook to find the definition or equation for each concentration unit. Write an equality (refer back to Dimensional Analysis Lab) that represents the concentration of the given example. Then write the two possible conversion factors that can be used in solving problems. The first example is done for you. Calculate the mass % (% m/m) NaCl of a solution made by dissolving 3.50 grams of NaCl in 50.00 grams of water.Explanation / Answer
1a) 10% by mass KNO3.(aq)
The solute is defined as the substance or chemical which when added into water or any liquid ( solvent) to produce an aqueous solution.
So KNO3 is the solute.
Water(H2O ) is the solvent.
Aqueous KNO3 is the solution.
b). Ethanol is the solute.
Water is the solvent
Wine is the final aqueous solution.
