–Compare the effect of temperature on the solubility of NaNO3 and Ce2(SO4)3 compounds. Explain the relationship between solubility and temperature as direct or inverse for each substance.

the answer is b. dilution

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.
