6.02 x 10^23 atoms of an element have a mass in grams equivalent to the mass of of the atoms in amu.
a) 1x 10-23
b) 1
c) 6.02
d) 1 x 1023

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.
