Answer: 127.5ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus 127.5 ml of 0.5M of HNO3 would be needed to react with 85ml of 0.75M of KOH
390 because im cool and awsome

the correct option is:
C. The changes make the theory stronger because it has been tested and edited multiple times, making it more durable.
2. In Rutherfords experiment,Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen;
A. All the alpha particles would be deflected by the foil because of the even distribution of mass and charge throughout the atom.
According to Thomson's plum pudding model of the atom the positive and negative charges are evenly distributed.
