how many grams of tin metal will be deposited from a solution that contains Sn2 ions if a current of 1.22 is applied for 71.6 minutes

i would say b

explanation:

but i think i would need more information than that

i think is conclusions.i think so

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.
