acetic acid has a melting point of 16.6 Celsius and a boiling point of 117.9 Celsius. Sketch a heating curve showing the phase changes of acetic acid. Clearly label all seven parts like we did in our notes.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
