Find the molarity of each solution. Which solution has the highest molarity? the highest density? Give your reasoning.
a. 1.0 g KCl in 1.0 L water
b. 5.0 g KCl in 0.5 L water
c. 10.0 g KCl in 0.3 L water

Let's not the following properties with the correspondent solution for one, the lowest electrical connectivity. This property matches up with a solution. Be because sucrose is a non electrolyte and it will not conduct electricity very well. Number two. The property is the lowest boiling points, and the lowest boiling point matches up with a solution. De because d 0.5 mol an A C l would have the least number of total ions present for three. The highest vapor pressure of water. The highest vapor pressure Yeah, of water at 25 degrees Celsius. So So Property three matches up with solution D and this once again, uh, this is the lowest small fraction of Salyut irons and a higher mole fraction of water. And for four, the property is the lowest freezing points and this matches up with a solution A and solution a 0.1. Moeller Casey l do the highest part concentration of ions present in the solution. It's

So if a problem 19 you have to find which, with the falling soldiers, experiences the greatest increase in entropy when dissolved in the water and when all of them is turning into an a clear solution, then you have to look for how maney ions each just Salyers, will produce. So for a we have a calcium chloride which has a total of three ions, one Kelis human to chlorine ions for via we have filled young bro online, which is just two miles for a C. We have calcium chloride, which is also to ions for D. We have chromium, nitrates or chromium three nitrates, which has a four total ions, one chromium ion and three nitrate ions. And for you we have lift young hydroxide, which is just two ions. So out of all of these d chromium 39 trade has the most ions and Dustin will experience the greatest increase in entropy when dissolved in water. And yeah, that's basically it's

So if a problem 19 and had to find out which of these I onlookers solids that will increase the entropy the most went dissolved in the water, and entropy increases when the number of moles of particles increases. So to find which one will increase entropy the greatest you just find which one has the most ions in this case is gonna be d chrome young 39 trade because it has a total of four ions one chromium, three ion and a three nitrate ions. All the other ones have, like two or three I'll. It's like calcium chloride has the three islands, one culture of my own and to chlorine ions. So then bromide and potassium chloride and lithium hydroxide all have two ions, So yeah, D chromium three nitrate. It's gonna increase. Interview the most went dissolved into water, and that's basically it

Let's discuss this problem from solutions and their physical properties where we are given two columns, one column has properties and other column has certain solutions. We will match the solution against the property given in the column on the left side, and also we will explain the reason. So the first one is the solution with lowest conductivity. So it is the B option. That is 0.15 mol L C. 12 at 22 0 11, because it is a non electrolyte, so it will not release it's irons. And hence there will be less a number of moles of solute and lessen electrical conductivity. The second one is a solution with lowest boiling point. It is the solution D that is point zero five moral n a seal that is sodium chloride solution, as the, uh, morality of salute is small list so it mix boiling point elevation off smallest value. The Taliban is the solution, having highest people pressure again. It is the solution D that is 0.5 moral sodium chloride solution, and the reason is as same in point number two, that is, the morality of the salute is smallest soul. More papers of water will be formed and hence more vapor pressure will be shown by this solution. The last one is the solution with lowest freezing point. So this will be the solution. A. That is 0.10 moral rotation chloride solution, because the morality of the salute here is highest. So these are the solutions with the property indicated and their reasons.
