The amount of Neon gas with the given volume and at the given temperature and pressure is 0.21 mol.
Option C) 0.21 mol is the correct answer.
What is Ideal Gas Law?
The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given that;
- Volume of the gas V = 0.84L
- Pressure P = 4.6atm
- Temperature T = 222K
- Universal gas constant R = 0.0821 Latm/molK
- Amount of gas n = ?
PV = nRT
n = PV / RT
n = ( 4.6atm × 0.84L ) / ( 0.0821 Latm/molK × 222K )
n = ( 3.864Latm ) / ( 18.2262Latm/mol )
n = 0.21 mol
Therefore, the amount of Neon gas with the given volume and at the given temperature and pressure is 0.21 mol.
Option C) 0.21 mol is the correct answer.
