The formula is 1.5RT, where R is the universal gas constant and T is the temperature in kelvin.
1.5(8.314 J/molK)(50+273.15)K(1 mol) = 4030J
1.5(8.314 J/molK)(50+273.15)K(1 mol) = 4030J
Answer:
4.030 kJ/mol is the average kinetic energy of 1 mole of a gas.
Explanation:
Average energy of 1 mol of gas:
[tex]K.E=\frac{3}{2}RT[/tex]
T = temperature of the gas molecule in Kelvins
R = Universal gas constant = 8.314 J/mol K
We have :
T = 50°C = 323.15 K
The average kinetic energy of 1 mole of a gas :
[tex]K.E=\frac{3}{2}\times 8.314 J/mol K\times 323.15 K=4,030.00 J/mol=4.030 kJ/mol[/tex]
(1 kJ = 1000 J)
4.030 kJ/mol is the average kinetic energy of 1 mole of a gas.
