What mass of oxygen forms from 71.89 g CO2? Use the periodic table to find molar masses.

answer: c.

explanation:

i believe the answer is 5,000

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.
