Drugs are sometimes used by athletes to enchance there performance. All medal-winning athletes are required to provide a urine sample at the end of their race. the urine samples are tested using chromatography to test for illegal substance. Describe the method used to explain how you would be able to tell whether illegal drugs have been taken?

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

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.
