Cabr2 will most likely dissolve in which solvent? 1. bi3 2. h2o 3. br2 4. ccl4 5. c8h18
77julia77 [94]
General principle of solubility is 'like dissolves like'

CaBr_{2} is an ionic compound, wherein the constituent ions (Ca^{2+} and Br^{-}) are held by electrostatic forces of interaction. 

Such ionic compounds are soluble in polar solvents. 

Among the solvent mentioned in question, water (H_{2}O) has maximum polarity. Hence, CaBr_{2} is most likely to dissolve in H_{2}O

Calculate the percent by mass of potassium nitrate in a solution made from 45.0 g kno3 and 295 ml of water. The density of water
Tanzania [10]

Answer:  the percent by mass of potassium nitrate is 13.3%

Explanation:

<u>1) Data:</u>

  • Mass of solute, m₁ = 45.0 g
  • Volume of solvent, V₂ = 295 ml
  • density of water, d₂ = 0.997 g/ml

<u>2) Formulae</u>:

  • Percent by mass, % = (mass of solute / mass of solution) × 100

  • Density, d = mass / volume

<u>3) Solution</u>:

  • d = mass / volume ⇒ m₂ = d₂ × V₂ = 0.997 g/ml × 295 ml = 294. g
  • mass of solution = m₁ + m₂ = 45.0g + 294. g = 339. g
  • % = (45.0 g / 339. g) × 100 = 13.3 %
  • The answer has to be reported with 3 significant figures.
