Calculate ℰ° values for the galvanic cells described below. (a) Zn(s) + Ag+(aq) equilibrium reaction arrow Zn2+(aq) + Ag(s)
(b) IO3-(aq) + Fe2+(aq) equilibrium reaction arrow Fe3+(aq) + I2(aq)

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.
