Calculate the mass of gold(III) chloride that contains a billion gold atoms. Be sure your answer has a unit symbol if necessary, and round it to 2 significant digits.

the answer would be a

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.
