Considering the definition of molar volume and ideal gas law, the molar volume of an ideal gas at 25∘C and 1 atm pressure is 24.436 $\frac{L}{mole}$ .

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T).

The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P×V = n× R× T

On the other hand, molar volume is a property that indicates how much space a mole of a certain substance or compound occupies.

The expression to calculate the molar volume is:

$Molar Volume=\frac{V}{n}$

where V is the volume it occupies, and n is the amount of the species in moles.

Then, rearranging the expression for the ideal gas law, you obtain:

$\frac{V}{n} =\frac{RxT}{P}$

$MolarVolume =\frac{RxT}{P}$

In this case, you know:

R= 0.082 $\frac{atmL}{molK}$ T= 25 C= 298 KP= 1 atm

Replacing:

$MolarVolume =\frac{0.082\frac{atmL}{molK} x298 K}{1 atm}$

Solving:

MolarVolume= 24.436 $\frac{L}{mole}$

In summary, the molar volume of an ideal gas at 25∘C and 1 atm pressure is 24.436 $\frac{L}{mole}$ .

Answer from: babycakes08d

24.5 liter / mol

Explanation:

1) Data:

a) T = 25°C = 25 + 273.15K = 298.15 K

b) P = 1 atm

c) assumption: ideal gas

2) Formulae and principles

a) Ideal gas equation: p V = n R T, where:

p = pressureV = volumen = number of molesR = universal constant of gases = 0.0821 atm-liter / K-molT = absolute temperature (Kelvin)

b) Molar volume: ν = V / n, where:

ν = molar volumeV = volumen = number of moles

3) Solution:

p V = n R T⇒ V/n = ν = RT / p =

= 0.0821 atm-liter / mol-K × 298.15 K / 1 atm

= 24.5 liter / mol

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
