How much heat will be released when 4.77 g of ethanol (C2H5OH) reacts with excess oxygen according to the following equation? C2H5OH + 3O2 → 2CO2 + 3H2O ΔH = -1366.7 kJ kJ (Your answer should have 3 sig figs.)

ok whats the question if not i cannot you i need question and need a thing to answer

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.
