116.6 x 10^{ -3} is the volume of methane contained in 2.50 L of a saturated solution at 25 ∘C that was extracted and placed under STP conditions.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

The solubility of methane in water at 25 degrees Celcius is 1.3 x 10^{ -3} M. It implies   1.3 x 10^{ -3} moles of methane are dissolved in one litre of water.

The number of moles of methane in 4 L of water can be calculated as follows:

Moles of methane = \frac{1.3 . 10^{ -3} }{1L} x\frac{4L}{1L}

Moles of methane = 5.2 x 10^{ -3}

STP refers to standard temperature and pressure. Under STP conditions, the temperature of the substance is  0 degrees celcius and its pressure is 1 atm.

An ideal gas is an imaginary gas comprising of a large number of randomly moving particles and the motion between such articles is considered to be perfectly elastic. The ideal gas equation describes the relationship between pressure, volume, temperature and number of moles of a gas.

The expression for ideal gas equation is as follows:

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 1 atm

V= ?

R= 0.082057338 \;L \;atm \;K^{-1}mol^{-1}

T=273K

n=?

Putting value in the given equation:

\frac{PV}{RT}=n

5.2 x 10^{ -3} = \frac{1 \;atm\; X \;V}{0.082057338 \;L \;atm \;K^{-1}mol^{-1} X 273}

V= 116.6 x 10^{ -3}

Hence, 116.6 x 10^{ -3} is the volume of methane contained in 2.50 L of a saturated solution at 25 ∘C was extracted and placed under STP conditions.

Calculate the average speed between 6 hours and 9 hours
Dominik [7]

Answer:

60 Miles per Hour

Explanation:

You included no scenario so I will develop a hypothetical that you can reference.

Assuming a car traveled a distance of 450 miles from one place to another in 9 hours with the car travelling 180 of those miles between 6 hours and 9 hours, what was the average speed between those 6 and 9 hours.

The car travelled 180 miles in 6hours - 9 hours.  First find out how many hours this is:

= 9 - 6

= 3 hours

Speed = Distance / Time

= 180 / 3 hours

= 60 miles per hour

A sample of gas has a volume of 400 liters when its temperature is 20.C and its pressure
ikadub [295]

Answer:

V₂ = 145.35 L

Explanation:

Given data:

Initial volume = 400 L

Initial pressure = 300 mmHg (300/760 =0.39 atm)

Initial temperature = 20 °C (20 +273 = 293 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

P₁V₁/T₁ = P₂V₂/T₂  

V₂ = P₁V₁T₂  /T₁ P₂

V₂ =  0.39 atm × 400 L × 273 K / 293 K × 1 atm

V₂ = 42588 atm.L.K /293 K.atm

V₂ = 145.35 L

A neutral atom of sulfur has the following characteristics:
Paraphin [41]

Answer: proton number = 16

Electron number =16

Neutron number =16

Explanation: Mass number = 32

Atomic number = 16

atomic number = proton number = 16.

Since the atom is neutral, proton number is the same as electron number i.e Electron number = proton number =16

Mass number = proton + Neutron

32 = 16 + Neutron

Neutron = 32 — 16 = 16

24. As the first five elements in Group 14 are considered in order from top to bottom, there are changes
myrzilka [38]

Answer:

B

Explanation:

As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.
