Mrs. Hill put 50g of sugar in water and watched the sugar dissolve. She then boiled the sugar water in a pan until it evaporated and the sugar was left at the bottom of the pan.
How much sugar was left?

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.
