0.650 moles of O₂(g) are added to 1.00 L flask and the internal pressure is measured at 20.00 atm. What is the temperature of the gas under these conditions (in *C)?___ °C ?

Answer:

T = 101.96 degrees

Step-by-step explanation:

We are given the following

Number of moles = 0.650 mol

Volume = 1.00 L

Pressure = 20.00 atm

We are going to use the ideal gas low which is given by:

pV = nRT

Therefore:


T\text{ = }(pV)/(nR)

We know R = 0.08206 L.atm/Kmol


\begin{gathered} T\text{ = }(20\ast1)/(0.65\ast0.08206) \\ T\text{ = 374.960 K} \end{gathered}

T(in degrees) = 374.96 - 273

= 101.96 degrees
