Estimate the liquid density (g/cm3) of propane at 298 K and 10 bar. Compare the price per kilogram of propane to the price of re

Deffense [45]

Answer:

Density of propane = 17.8 g/L

Propane is more priced than gasoline

Explanation:

Given:

Temperature, T = 298 K

Pressure, P = 10 bar = 0.987 × 10 = 9.87 atm

now,

Molar mass of propane, M = 44.1 g/mol

From ideal gas law

⇒ PV = nRT

here,

n is the number of moles

R is the ideal gas constant = 0.0821 L.atm/mol.K

also,

Density, D = $\frac{\textup{Mass}}{\textup{Volume(V)}}$

or

V = $\frac{\textup{Mass}}{\textup{D}}$

and,

nM = mass

thus,

V = $\frac{\textup{nM}}{\textup{D}}$

substituting in the ideal gas relation

we have

P = $\frac{\textup{DRT}}{\textup{M}}$

or

D = $\frac{\textup{PM}}{\textup{RT}}$

or

D = $\frac{9.87\times44.1}{0.0821\times298}$

or

D = 17.8 g/L

Now,

1 gallon = 3.78 Liter

Therefore,

5 gallon = 5 × 3.78 Liter = 18.9 Liter

Thus,

mass of 5 gallon propane = Volume × Density

= 18.9 Liter × 17.8 g/L

= 336.42 g

or

= 0.336 kg

also it is given that Price of 5 gallon propane i.e 0.336 kg = $30

Therefore,

Price per kg = $\frac{30}{0.336}$

= $89.28

and,

Mass of 5 gallons i.e 18.9 Liter gasoline = Density × Volume

= 0.692 g/cm³ × 18.9 Liter

also,

1 L = 1000 cm³

thus,

= 0.692 g/cm³ × 18.9 × 1000 cm³

= 13078.8 g

or

= 13.078 kg

Therefore,

Price per kg of gasoline = $\frac{\$30}{13.078}$

= $2.29

hence, propane is more priced than gasoline

Assume that microbrewery beer is a normal good. Prices of microbrewery beer have risen steadily in recent years. Over this same

Shkiper50 [21]

Answer:

The correct answer is option D.

Explanation:

Microbrewery beer is a normal good. Its prices have increased recently in recent years. The prices for fermenting vats used in beer have also risen and the consumer income has fallen.

Since beer is a normal good an increase in its price and decrease in the consumer income will decrease its demand. As a result, the demand curve will move to the left, decreasing the price of the product.

At the same time, the increase in the price of fermenting vats will increase the cost of producing beer. This will cause the supply of beer to decrease.

This will cause the supply curve to shift to the left. If the leftward shift in the supply curve is more than the leftward shift in demand, the price of beer will increase.

allochka39001 [22]

Answer: $89,550

Explanation:

When capitalizing the cost of a fixed asset, all the costs that were associated with acquiring it and setting it up for use are to be capitalized. This includes the cost of purchase, transportation and installation.

Periodic costs are to be expensed.

Cost to be capitalized:

= Purchase price + Installation price + Cost of critical test (this is needed to find out if the machine is operate appropriately so should be capitalized)

= 85,000 + 2,950 + 1,600

= $89,550
