Question

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

Answer 1

Answer:

$81.20\text{ K}$

Explanation:

Here, we want to calculate the temperature

Mathematically from the ideal gas equation:

$\begin{gathered} PV\text{ = nRT} \\ Thus: \\ T\text{ = }\frac{PV}{nR} \end{gathered}$

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:

$T\text{ = }\frac{2\times10}{3\times0.0821}\text{ = 81.20 K}$
