Which of the following mass measurements has 3 significant figures? O 13.30 g
O 13.3 g
O 13.3 mL
O 0.013 kg

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.
