Answer:
8.73 L
Explanation:
First, you need to convert grams to moles using the molar mass.
Molar Mass (N₂): 2(14.009 g/mol)
Molar Mass (N₂): 28.018 g/mol
12.2 grams N₂ 1 mole
---------------------- x ------------------------ = 0.435 moles N₂
28.018 grams
To find the volume, you need to use the Ideal Gas Law:
PV = nRT
In this equation,
-----> P = pressure (torr)
-----> V = volume (L)
-----> n = moles
-----> R = Ideal Gas constant (62.36 torr*L/mol*K)
-----> T = temperature (K)
After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation.
P = 1132 torr R = 62.36 torr*L/mol*K
V = ? L T = 91 °C + 273.15 = 364.15 K
n = 0.435 moles
PV = nRT
(1132 torr)V = (0.435 moles)(62.36 torr*L/mol*K)(364.15 K)
(1132 torr)V = 9888.015
V = 8.73 L
The root mean square speed of a gas is calculated through the equation,
Vrms = sqrt (3RT/M)
where:
Vrms = root mean square velocity/speed
R = universal gas constant
T = temperature
M = molar mass of the gas
Fluorine gas is a diatomic particle, F2, with a molar mass equal to 37.997 g/mol. Substituting the known values to the equation,
Vrms = sqrt (3)(0.0821 L.atm/mol.K)(425 + 273.15)) / 37.997 g/mol))
Vrms = sqrt ((3)(0.0821 L atm)(101325 kg/ms²/1 atm))(698.15 K) (1 m³/1000L)/ (37.997 g)(1 kg/1000g))
Vrms = 25.63 m/s
ANSWER: 25.63 m/s
Answer:
3) The amount of matter within the system remains the same
5) The cycle has a well-defined starting and stopping point.
Explanation:
A closed system is a system that the boundaries of a system cannot be passed by either matter or energy.
Hence, generalisations can be made based on a closed system and the law of conservation of mass which states that matter can neither be created nor destroyed but can only change form.
The sun does not orbit anything everything orbits the sun and I don't think the solar system orbits anything I'm sorry
Answer:
the frequency with get lower
