Question

Calculate the temperature of 3 moles of O2 with the pressure of 2atm and a volume of 10L.

Answer 1

`81.20\text{ K}`

Step-by-step explanation:

Here, we want to calculate the temperature

Mathematically from the ideal gas equation:

`\begin{gathered} PV\text{ = nRT} \\ Thus: \\ T\text{ = }(PV)/(nR) \end{gathered}`

Where:

T is the temperature in Kelvin which we want to calculate

P is the pressure which is given as 2 atm

V is the volume which is given as 10L

n is the number of moles which is given as 3

R is the molar gas constant which is 0.0821 L.atm/mol.k

Substituting the values, we have it that:

`T\text{ = }(2*10)/(3*0.0821)\text{ = 81.20 K}`
