What is the kinetic energy in kJ of 1 mole of water molecules (mass=18) if the average velocity is 590 m/s (1300 mph)

= 3132.9 Joules

Explanation:

Kinetic energy is the energy possessed by a body when in motion. Kinetic energy is calculated by the formula; K. E = 1/2 mV², where m is the mass of the body or object, and V is the velocity. Therefore kinetic energy depends on the mass and the velocity of the body or the object in motion.

In this case;

Kinetic energy = 0.5 * 0.018 kg * 590²

= 3132.9 Joules
