Substance D is sugar. We heated it up over a flame to 135 degrees Celsius and it melted and then burned. We were able to dissolve some of it in water, but it didn't conduct electricity. Is substance D ionic or molecular?

catya your not at all which answer i've seen you do this on another question!

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.
