Answer:

63.33%

Explanation:

To find the percentage of sugar in the milk chocolate just divide 15 by 9.5. This will give you 0.63333 (recurring). To find the percentage, times it by 100, which will give you 63.33%.

Hope this helped :)

a 1.00-l solution contains 2.50×10-4 m cu(no3)2 and 1.20×10-3 m ethylenediamine (en). the kf for cu(en)22 is 1.00 × 1020. chegg

Debora [2.8K]

The concentration of copper in the solution is

$5.1 \times 10^{18} \: M.$

The volume of the solution = 1.00 L

$Moles \: of \:Cu(NO_{3}) _{2} = 2.50 \times 10 {}^{ - 4}$

$Moles \: of \: Ethylenediamine = 1.20 \times 10.3$

$k _{f} = 1.00 \times 10^{20}$

Overall balanced equation of reaction is,

$Cu^{2 + }(aq) \: + 2en \: (aq)→ Cu(en) ^{2 + }_{2}(aq)$

$Moles \: of \:Cu(NO_{3}) _{2} =0.00025 \: mol$

Mole ratio for,

$Moles \: of\:Cu(NO_{3}) _{2}: en$

$2: 1$

$Moles \: of \: en = 0.000250 \times 2$

$= 0.00050 \: moles$

Remained moles of en are= (0.00120-0.000500)

$= 0.000700 \: moles$

The concentration of copper in the solution is,

$k_{f} = \frac{Cu(en)^{2 + }_{2} }{Cu^{2+}en^{2} }$

$1.00 \times 10 ^{20} = \frac{0.000250}{(Cu )^{2 +} \times (0.000700)^{2 + } }$

$= 5.1 \times 10^{18} \: M.$

Therefore, the concentration of copper in the solution is

$5.1 \times 10^{18} \: M.$

Papessa [141]

Answer:

Cystic fibrosis (CF) is a genetic disease that causes thick, sticky mucus to build up in organs, including the lungs and the pancreas. In a healthy person, mucus that lines organs and body cavities, such as the lungs and the nose, is slippery and watery. In people with CF, thick mucus clogs causes symptoms in the lungs and pancreas.
