What pressure is exerted by 0.90 moles of gas at 50 C if the gas is in a 1.25 L container?

Chemistry

Answer:

19.07 atm

Explanation:

Data obtained from the question include the following:

Number of mole (n) = 0.9 mole

Temperature (T) = 50°C = 50°C + 273 = 323K

Volume (V) = 1.25L

Pressure (P) =...?

Note: the gas constant (R) = 0.082atm.L/Kmol

The pressure exerted by the gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

P = nRT /V

P= (0.9 x 0.082 x 323)/1.25

P = 19.07 atm

Therefore, the pressure exerted by the gas is 19.07 atm

zysi [14]

E

All the other chices give evidence that supports that hypothesisthat the Moon was made of material that was flung off Earth during a time when it was rapidly spinning.

Explanation:

There is an enormous amount of similarities between the minerals in the moon rocks and the rocks on earth, except that for some minerals, like potassium, their quantities are higher on the earth than on the moon.

However, there is still supports for the evidence (by the other choices) that the moon was made from a piece of earth ejected from asteroid impact in primordial earth.Explanation:It’s believed that more than 3.5 billion years during the formation of earth and before it had cooled there were frequent asteroid impacts and one enormous collision ejected a large piece of molten earth into space but within earth’s gravity influence. This piece formed the moon. Evidence of asteroid impacts are frozen in time on the moon surface thanks to the fact that the moon has no atmosphere or tectonic plates movements that wipe off this ‘evidence’.

Alex777 [14]

45 m. If each student needs 750 mm of tubing, the teacher should order 45 m of tubing.

a) Find the <em>length in millimetres</em>

Length = 60 students x (750 mm tubing/1 student) = 45 000 mm tubing

b) Convert <em>millimetres to metres </em>

Length = 45 000 mm tubing x (1 m tubing/1000 mm tubing) = 45 m tubing

1. A gas having the following composition is burnt under a boiler with 50% excess air.
jeka94

The composition of the stack gas are :

CH_4= 0.8713

C_3H_8 = 0.0202

CO = 0.107

<h3 /><h3>What is a mole fraction?</h3>

The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.

Assuming 100 g of the stack gas. Calculate the mass of each species in this sample according to their percentages.

Mass of CH_4 : 70% of 100 g = 70 g

Mass of C_3H_8 : 15% of 100 g = 15 g

Mass of CO : 15% of 100 g = 15 g

Now calculate the number of moles of each species:

Number of moles of CH_4 : \frac{70 g}{16.04 g/mol} = 4.3 mole

Number of moles of C_3H_8: \frac{15 g}{144.1 g/mol} = 0.10 mole

Mass of CO : \frac{15 g}{28.01 g/mol} = 0.53 mole

Now to calculate the mole fraction of each we use the formula:

Mole fraction of CH_4: \frac{4.3}{4.935} = 0.8713

Mole fraction of C_3H_8 : \frac{0.10}{4.935} = 0.0202

Mole fraction of CO : \frac{0.53}{4.935} = 0.107

Hence, composition of the stack gas are:

CH_4 = 0.8713

C_3H_8 = 0.0202

CO = 0.107
