Of the substances that did diffuse through the dialysis tubing, did all of the molecules/ions of that substance diffuse into the dialysate? Explain.

the answer is c i believe

50.23 i believe is correct but don't quote me on that.

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.
