Determine the precent composition of the following compounds:

a) iron(ii)hydroxide
b) iron(ii)oxide

the answer is c i believe

girl imma just put my comment here because i need a couple point okurrttt

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.
