A $\mathrm{KNO}_{3}$ solution is made using $88.4 \mathrm{g}$ of $\mathrm{KNO}_{3}$ and diluting to a total solution volume of 1.50 L. Calculate the molarity and mass percent of the solution. (Assume a density of $1.05 \mathrm{g} / \mathrm{mL}$ for the solution.)

Using the information given for a. We're going to calculate the percent by volume, which would be equal to the volume of the substance, which is the 12.8 mil leaders divided by the volume of the solution just 75 milliliters times 100% and this will yield a percent by volume. That's equal to 17.1% for be. We're calculating the percent by mouths. So we have to calculate the mass of the salutes, which would be equal to the volume 12.8 mil leaders tons of density 0.803 grams permanent leaders and this will yield the mouth of saw equal to 10.27 grams. The mass of the solution would be equal to 75 milliliters, comes the density 0.988 grams per milliliters and this would be equal to 74.1 grams. Therefore, the percent by mass would be equal to 10.27 grams over 74.1 grams times 100% which would deal the percent of 13.8% for C, the percent mass volume mass volume from Part B. We solved the mass of the I saw you two is 10.27 grams. The volume 75 milliliters of the solution comes 100% and the percent mass volume works up to 13.7%. Okay?

Um, contextual information are mullah Solid ability is the number of moles of a substance that can be dissolved polluter of solution. After the solution has achieved saturation. So it could be calculated from the substance is solid ability product constant which is our chaos p value that we've looked at before where we need to incorporate our strike you metric coefficients now. So the units are most police. However, sometimes that Britain has just m which is what I've done here in this example. So we're calculating the mall Asali ability of S e c 03 So I've redefined my concentration times as values of us and then take my Sony Ability product tsp expression on. I replaced my concentration values in the square brackets with us, which leads me to have an s squared expression where we then need to square Ruark A s P value which generates Amal Assani ability, which is also represented by the letter s as 5.54 times 10 to minus six as our model Asali ability off f e c 03

To calculate mass percent. We need to know the mass of the salute and then we need to divide that by the mass of the solution and then multiply by 100. With more clarity. We don't know the mass of the salute. We know the moles of the solute and we don't know the mass of the solution. We know the leaders of solution. So a three molar solution has three moles of solute per liter solution. If it's sodium hydroxide we can convert the sodium hydroxide into grams by multiplying by the molar mass. And then we can convert the leaders of solution into milliliters by dividing by 1000 and then convert the mill leaders of solution into graham solution in the denominator by dividing by density. Well then multiply that by 100 to get percentage and we get 10 7% sodium hydroxide. We'll do the same thing with everything else will take our polarity which is to find as moles per liter, convert the moles of solute into grams by multiplying by the molar mass, convert the leaders of solution into mill leaders, convert the mill leaders using density into grams will then multiply by 100 to get a percentage, 2.75% potassium hydroxide. For the next one we have a six molar ammonia solution will convert the six miles ammonia into grams ammonia by multiplying by the molar mass, Then convert the leaders of solution into mill leaders and then the milliliters of solution into grams. Using density and we get 10.7% for the last one. We have a one molar solution of potassium or sodium carbonate, convert the grams are the mold sodium carbonate into grams by multiplying by the molar mass and then convert the leaders of solution into middle leaders and the mill leaders into grams. Using density multiplied by 100 to get a percentage and we get 9.64% sodium carbonate

In order to solve this problem, we first need to perform a couple of calculations on the concentration value 1.24 moles per liter. We can convert the denominator to melt leaders. Then we can use the density where Centimeters Cube is equal to milliliters and take the reciprocal. And then we can use the molar mass of potassium iodide. That last percent comes out to 0.179 grams of potassium iodide, where every gram of solution from here we can see that if the total grams of solution is one and we can subtract number of grams of potassium iodide that gives us the number of grams of water. And this allows us to set up a ratio of the massive potassium iodide to the mass of water, which we can easily use to calculate the morality. We first need to divide by the molar mass of potassium iodide and then convert the denominator in two kilograms. This gives us a morality value of 1.31 Molo in Part B. We're assuming complete association, and we're trying to calculate the new freezing point of the solution and we can use the equation for freezing point depression where I equals two. The freezing point depression value comes out to 4.89 degrees Celsius. This means that the freezing point is zero degrees minus 4.8 nine degrees negative 4.89 degrees Celsius. However, in part C, we're told that the actual freezing point is negative 4.46 degrees. So we can use this value along with the equation, to calculate what the actual event Hough factor is given that we know the morality and the Van Toff actor turns out to be 1.83 now, in order to figure out the percentage that actually dissociates, we need to subtract one from this value. And what we see is that 83% of potassium iodide molecules associate
