QUESTION 16 The solubility of an unknown salt is shown in the graph. If a solution is unsaturated at 30 °C, what happens when the solution is cooled? 150 140 130 170 110 100 90 80 70 60 40 30 10 O 10 20 30 40 50 60 70 80 90 100 Temperature Mg O The mass of the salt in the solution will increase. The mass of the salt in the solution will decrease. O The mass of the salt in the solution will remain the same. O It is unknown if the mass of the salt in the solution will remain the same or decrease. Solublity (mass in g of solutel per 100.0 g of water

! T 1 A Z The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). -6 Note: "major" chemical species are those present in concentrations greater than 10 mol/L. 89 FI compound propylene glycol Explanation ammonium lodide @ 2 glycerol W S X command Check 30: F2 # 3 formula C,H, (OH)₂ C₂H₂O, NH₂L 20 E E D 8.0 F3 C $ 4 R major species present when dissolved in water F a F4 % 5 V 0 0 T I F5 G 6 B F6 Y 7° H X & 7 00 stv N K F7 U 0.0.... 3 J © 2023 McGraw Hill LLC.

Understanding how solubility varies with temperature and pressure.

A student dissolves 1.9 g of styrene (C,H,) in 150. mL of a solvent with a density of 1.02 g/mL. The student notices that the volume of the solvent does not change when the styrene dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity = x10 molality 미□

Concentrated sulfuric acid is 98.0 % H₂SO4 by mass. Calculate the molarity of this solution if the density of 1.83 g/mL. 18.0 M 0.016 M 6.01 M 3.22 M

The solubility of CuBr in water at 25 °C is measured to be 0.010 L Round your answer to 2 significant digits. 0 Dx1 x10 Ś Use this information to calculate K for CuBr. sp
