A 15.267 g sample of a sulfide of gold was found to contain 12.272 g of gold, and the rest, sulfur. Determine the empirical formula of this sulfide of gold.

c) should be the answer.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

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.
