100ml of carbon monoxide (CO) is reacted with 40ml of oxygen (O2). What volume in mL of carbon dioxide (CO2) is formed? 2CO + O2 --> 2CO2

not clear

the objects have the same charge.

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.
