What does molality measure?
lisov135 [29]

Answer:

Molality measure C. Concentration

Explanation:

Molality is used to measure concentration of solute molecule present in a solution.Molality represent the presence of total number of solute molecules  in a kilgram of solvent.

      For exam if 6 moles of a solute is present in 1 kg of solvent then the concentration of that solute molecule will be 6 molal.The SI unit of molality is mole/kg or milimole/gram.

Here is the information: A 1.2516 gram sample of a mixture of CaCO3 and Na2SO4 was analyzed by dissolving the sample and adding
tiny-mole [99]

Answer:

93,32 % (w/w)

Explanation:

The Ca²⁺ of CaCO₃ was completely precipitate to CaC₂O₄ that results in H₂C₂O₄. The titration of this one is:

3H₂C₂O₄ + 2H⁺ + MnO₄⁻ → Mn²⁺ + 4H₂O + 6CO₂

As you required 35,62mL of 0,1092M MnO₄⁻, the moles of H₂C₂O₄ are:

0,03562L×\frac{0,1092M}{L} =

3,890x10⁻³mol of MnO₄⁻×\frac{3molH_{2}C_{2}O_{4}}{1mol MnO_{4}^-} = <em>0,01167 mol of H₂C₂O₄</em>

The number of moles of CaCO₃ are the same number of moles of H₂C₂O₄ because every Ca²⁺ was converted in CaC₂O₄ that was converted in H₂C₂O₄. That means: <em>0,01167 mol of CaCO₃</em>

0,01167 mol of CaCO₃ are:

0,01167 mol of CaCO₃×\frac{100,0869g}{1mol} = <em>1,168 g of CaCO₃</em>

As the mass of the initial mixture is 1,2516 g, the percentage by weight of CaCO₃ is:

\frac{1,168g}{1,2516g}×100 = <em>93,32 % (w/w)</em>

I hope it helps!
