While performing the Acid-catalyzed Hydrolysis of Epoxides experiment you used a solution containing 1.84 mL of cyclohexene oxid
Elenna [48]

Answer:

The moles of starting material is 1.8212 \times 10^{-2} mole

Explanation:

Given:

Cyclohexene oxide material is used

Density = 0.97\frac{g}{mL}

Volume = 1.84  mL

Formula of Cyclohexene oxide = C_{6} H_{10} O

Molar mass is given by,

C = 6 \times 12 = 72

H = 10 \times 1 = 10

O = 1 \times 16 = 16

⇒ m' = 96\frac{g}{mol}

Mass m = 0.97 \times 1.84 = 1.7848 g

Moles is given by,

  n = \frac{m}{m'}

  n = \frac{1.7848}{98}

  n = 1.8212 \times 10^{-2} mol

Therefore, the moles of starting material is 1.8212 \times 10^{-2} mole

Answer:

The value of the Golden Igloo is $227.4 million.

Explanation:

First, we need to find the inner and the outer volume of the half-spherical shell:

V_{i} = \frac{1}{2}*\frac{4}{3}\pi r_{i}^{3}

V_{o} = \frac{1}{2}*\frac{4}{3}\pi r_{o}^{3}

The total volume is given by:

V_{T} = V_{o} - V_{i}

Where:

V_{i}: is the inner volume

r_{i}: is the inner radius = 1.25/2 = 0.625 m

V_{o}: is the outer volume

r_{o}: is the outer radius = 1.45/2 = 0.725 m

Then, the total volume of the Igloo is:

V_{T} = \frac{2}{3}\pi r_{o}^{3} - \frac{2}{3}\pi r_{i}^{3} = \frac{2}{3}\pi [(0.725 m)^{3} - (0.625 m)^{3}] = 0.29 m^{3}

Now, by using the density we can find the mass of the Igloo:

m = 19.3 \frac{g}{cm^{3}}*0.29 m^{3}*\frac{(100 cm)^{3}}{1 m^{3}} = 5.60 \cdot 10^{6} g

Finally, the value (V) of the antiquity is:

V = \frac{\$ 1263}{oz}*5.60 \cdot 10^{6} g*\frac{1 oz}{31.1034768 g} = \$ 227.4 \cdot 10^{6}  

Therefore, the value of the Golden Igloo is $227.4 million.

I hope it helps you!
