Ans 9.8 :
Molar mass of oxygen = 31.998 g/mol
mass of single molecule = 31.998 / (1000 x 6.022 x 1023)
= 5.3136 x 10-26 kg
Kinetic energy is given as :
K.E = 1/2 mv2
putting values :
= 1/2 ( 5.3136 x 10-26 kg) (1.5 x 103 m/s)2
= 6.0 x 10-20 J

In travelling a distance of 0.5m, an object gained 200 Joules of kinetic energy. What work was done on the object, assuming no frictional forces acted? What was the average forces acting on the object? If a force of 600N had acted over the same distance, what would have been the gain in kinetic energy?

Q) What is the kinetic energy, in joules, of a molecule of oxygen moving at a speed of 255 m/s(use the appropriate prefix to avoid exponential notation) a) The equation for kinetic energy is ½mv2, and is in units of joules. What are the component units for joules in terms of mass and velocity? kg m^2/s^2 b) From the previous part, we know that the mass needs to be in units of kg. What is the mass of an oxygen...
