What is the total motional contribution to the molar internal energy of gaseous H₂O at 25 $\circ$ C?

Question

Quizplus · Accepted Answer

The total motional contribution to the molar internal energy can be calculated using the equipartition theorem: U = (3/2)RT, where R is the gas constant and T is the temperature. Using the molar mass of gaseous H₂O (166.28 g/mol) and the given temperature of 25°C (298 K), we can calculate the total motional contribution: U = (3/2)(8.314 J/mol·K)(298 K) = 7.43 kJ/mol. Therefore, the answer is B, 7.43 kJ/mol.
