Answer:
Explanation:
Hello,
In this case, the dissociation of calcium fluoride is:
And the equilibrium expression is:
Which is useful to compute the molar solubility, symbolized by as the reaction extent:
In such a way, since the solubility product of calcium fluoride at 25 °C is 3.45x10⁻¹¹, the molar solubility is found to be:
And the solubility, considering its molar mass 78.08 g/mol is:
Regards.
Answer:
ΔTb = 0.66 C
Explanation:
Given
Mass of KBr = 185 g
Mass of water = 1.2 kg
Kb = 0.51 C/m
Explanation:
The change in boiling point (ΔTb) is given by the product of molality (m) of the solution and the boiling point constant (Kb)
[tex]\Delta T_{b}= 0.51 C/m * 1.296 m = 0.66 C[\tex]
X=107 because the sides of a hexagon must add up to 720
