Your first titration required 25.76 mL of 0.111 M NaOH to titrate a .213 g sample of your unknown diprotic acid. What is the molar mass of your acid

answer; /// i do believe that the correct answer is (c)nuclear bond

first one is the correct answer

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.
