When 16.0 g of an unknown compound (a nonelectrolyte) are dis solved in exactly 800. g of water, the solution has a freezing poi
dexar [7]

Answer:

A. 266g/mol

Explanation:

A colligative property of matter is freezing point depression. The formula is:

ΔT = i×Kf×m <em>(1)</em>

Where:

ΔT is change in temperature (0°C - -0,14°C = 0,14°C)i is Van't Hoff factor (1 for a nonelectrolyte dissolved in water), kf is freezing point molar constant of solvent (1,86°Cm⁻¹) and m is molality of the solution (moles of solute per kg of solution). The mass of the solution is 816,0g

Replacing in (1):

0,14°C = 1×1,86°Cm⁻¹× mol Solute / 0,816kg

<em>0,0614 = mol of solute</em>.

As molar mass is defined as grams per mole of substance and the compound weights 16,0g:

16,0g / 0,0614 mol = 261 g/mol ≈ <em>A. 266g/mol</em>

I hope it helps!

Question 10
bixtya [17]
The reaction that should be followed is
Na2SO4 + C<span>a(NO3)2 --> CaSO4 + 2NaNO3</span>
first calculate the limiting reactant
mol Na2SO4 = 0.075 L (<span>1.54×10−2 mol / L) = 1.155x10-3 mol


mol Ca(NO3)2 = 0.075 L (</span><span>1.22×10−2 mol / L) = 9.15x10-4 mol
so the limiting reactant is the Ca(NO3)2

so all of the Ca2+ will be precipitated, percentage unprecipitated = 0.00 % </span>

The density of titanium metal is 4.51 g/cm3 at 25 ∘C What mass of titanium displaces 68.6 mL of water at 25 ∘C∘C?
goblinko [34]

Answer:

The mass of titanium displaces 68.6 mL of water is 309.4 g.

Explanation:

Given that:-

\rho=4.51\ g/cm^3

V=68.6\ mL

Also, 1 cm^3  = 1 mL

So, V=68.6\ cm^3

The expression for the calculation of density is shown below as:-

\rho=\frac{m}{V}

Using the above expression to calculate the mass as:-

m={\rho}\times V

Applying the values to calculate the mass as:-

m=4.51\ g/cm^3\times 68.6\ cm^3=309.4\ g

<u>The mass of titanium displaces 68.6 mL of water is 309.4 g.</u>
