For changing potential energy; When you drop a book, gravitational potential energy is transformed into kinetic energy. Your car transforms the chemical potential energy stored in gasoline into the kinetic energy of the car's motion.
For Kinetic Energy; kinetic energy can be converted into electrical energy by a generator or into thermal energy by the brakes on a car.
NO.OF.MOLES= MASS/ATOMIC MASS THE ATOMICITY OF SULPHUR IS 8 AND ITS MASS NUMBER IS 32. SO, THE ATOMIC MASS IS 256 NO.OF.MOLES= 53.7/256 = 537/2560 = 0.2097
