CH4 + 202 = CO2 + 2H2O

If you are given 64.0 grams of CH4, how many grams of H20 are made?

answer; economic order quantity;

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.
