0.16 mol of argon gas is admitted to an evacuated 70 cm^3 container at 30°C. The gas then undergoes an isothermal expansion to a

Semmy [17]

Answer:

The final pressure of the gas is 9.94 atm.

Explanation:

Given that,

Weight of argon = 0.16 mol

Initial volume = 70 cm³

Angle = 30°C

Final volume = 400 cm³

We need to calculate the initial pressure of gas

Using equation of ideal gas

$PV=nRT$

$P_{i}=\dfrac{nRT}{V}$

Where, P = pressure

R = gas constant

T = temperature

Put the value in the equation

$P_{i}=\dfrac{0.16\times8.314\times(30+273)}{70\times10^{-6}}$

$P_{i}=5.75\times10^{6}\ Pa$

$P_{i}=56.827\ atm$

We need to calculate the final temperature

Using relation pressure and volume

$P_{2}=\dfrac{P_{1}V_{1}}{V_{2}}$

$P_{2}=\dfrac{56.827\times70}{400}$

$P_{2}=9.94\ atm$

Hence, The final pressure of the gas is 9.94 atm.

Can a higher mass-to-light ratio mean that there is gas and dust present in the system that is being analyzed?

kramer

Answer:

mass-to-light ratio is the ratio of the mass of a body and the light output it has. it is represented by in terms of a single number and and tells us about the kind of stars making up the most luminous population in a galaxy. the mass-to-ratio of stars is greater than 1, for dark matter is 100 times high and very low for dust. higher mass-to-ratio mean that in a galaxy on average every solar mass emits a light less than the sun of the earth solar system does.

the large mass-to-light ratio shows that gas and dust is being analyzed.
