A student fills up a graduated cylinder to 5.0 mL with ethylene glycol. The graduated cylinder empty had a mass of 36.2 g, but now has a mass of 42.2 g. Find the density of the ethylene glycol.

answer carbon and three oxygen atoms;

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.
