what is the correct numerical setup for calculating the volume of h2(g) produced if the conditions are changed to STP

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )

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.
