The maximum concentration (in m) of calcium ions[Ca^{2+}] in the given solution is 6.2×10^{-8}

The balanced equillibrium equation is ,

CaCO_{3} (s) ↔ Ca^{2+}(aq) + CO_{3} ^{2-}(aq)

From the reaction equation above, the formula for Ksp:

Ksp = [Ca^{2+}][  CO_{3} ^{2-}] = 3.4×10^{-9}

We know the value for [ CO_{3} ^{2-}] , so we can solve for [Ca^{2+}]as:

( 3.4×10^{-9}) = [Ca^{2+}] (0.055)

[Ca^{2+}] = 61.8×10^{-9}

[Ca^{2+}] = 6.2×10^{-8}

Therefore, the maximum concentration (in m) of calcium ions[Ca^{2+}]  in the given solution is 6.2×10^{-8}

When 2.69 g 2.69 g of a nonelectrolyte solute is dissolved in water to make 345 mL 345 mL of solution at 26 °C, 26 °C, the solut
Gre4nikov [31]

Answer:

The molar concentration of this solution is 0.0463 mol/L

Explanation:

Step 1 : Data given

Mass of a nonelectrolyte solute = 2.69 grams

Volume of water = 345 mL = 0.345 L

Temperature = 26.0°CC = 273 + 26 = 299 K

The osmotic pressure = 863 torr

⇒ 863torr /760 = 1.13553 atm

Step 2: Calculate the molar concentration of this solution

Π = i*M*R*T

⇒with Π = the osmotic pressure = 1.13553 atm

⇒with i = the van't Hoff factor of the nonelectrolyte solute = 1

⇒with M = the molar concentration = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 299 K

1.13553 atm = 1 * M * 0.08206 L*atm/mol*K * 299 K

M = 1.13553 / (0.08206*299)

M = 0.0463 mol/L

The molar concentration of this solution is 0.0463 mol/L
