Answer: 1.11 atm
Explanation:
The unit of pressure include kilopascal (kPa), atmospheres (atm), mmHg etc
Now, given that:
Air pressure = 113 KPa
Convert kPa to atm
If 101.325 kPa = 1 atm
113 kPa = Z atm
To get the value of Z, cross multiply
Z atm x 101.325 kPa = 1 atm x 113 kPa
Z = ( 1 atm x 113 kPa) / 101.325 kPa
Z = 1.11 atm
Thus, the pressure is 1.11 atm
Let's assume that H₂ gas has ideal gas behavior.
Then we can use ideal gas formula,
PV = nRT
Where,
P = Pressure of the gas (Pa)
V = Volume of the gas (m³)
n = moles of the gas (mol)
R = Universal gas constant (8.314 J K⁻¹ mol⁻¹)
T = Temperature in Kelvin (K)
But,
n = m/M,
Where m is mass of the gas (kg) and M is molar mass of the gas (kg/mol)
Hence PV= mTR / M
P = mTR / VM = (m/V)TR / M
m/V = d (density (kg/m³)
By rearranging,
P = dRT / M
d = 0.135 g/L = 0.135 kg/m³
T = (273 + 201) K = 474 K
M = 2 g/mol = 2 x 10⁻³ kg/mol
From substitution,
P = 0.135 kg/m³ x 8.314 J K⁻¹ mol⁻¹ x 474 K / 2 x 10⁻³ kg/mol
P = 266006.43 Pa
P = 266 kPa
Hence the pressure of H₂ gas at 201⁰C is 266 kPa
I found this on google
“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”
I hope this helps
