How many formula units of NaCl constitute 1.25g of NaCl

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

c. 75.7

i think that is the right

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.
