Chemistry Tuition Singapore – The Mole Misconceptions   Misconception 1 The relative molecular mass of water (H20) is 18 g. Correct Concept   Both the relative atomic mass and the relative molecular mass have no units. Thus, the relative molecular mass of water is just 18.   Misconception 2   The mass of one hydrogen atom is 1.0 g. Correct Concept The mass of 1.0 mol (6 x 1023) hydrogen atoms is 1.0 g.   Please contact Angie @ 96790479 or Mr Ong @ 98639633 if you need Secondary 3-5 or O level or N level Chemistry Tuition /Secondary Physics Tuition

Physics Tuition Singapore – Energy,Work and Power Misconceptions   Misconception 1 Kinetic energy is a vector quantity and its direction is the same as the direction of motion of the object. Correct Concept Kinetic energy is a scalar quantity and does not have direction. Its magnitude depends on mass and speed (which is equal to the magnitude of velocity).   Misconception 2 A car travels from the top of a hill down a slope. Neglecting frictional forces, the final kinetic energy of the car is equal to the loss of potential energy. Correct Concept A car travels from the top of a hill down a slope. Neglecting frictional forces, the increase in kinetic energy of the car is equal to the loss of potential energy. Therefore, the final kinetic energy = initial kinetic energy – ...
