A 425.00 gram sample of a compound decomposes into 196.01 grams of carbon, 41.14 grams of hydrogen, 130.56 grams of oxygen, and 57.29 grams silicon. Experiments have shown the compound has a molecular weight of 208.329. What is the molecular formula?

i'm pretty sure its b i might be wrong though!

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.
