An analytical laboratory balance typically measures mass to the nearest 0.1 mg. You may want to reference (Page) Section 21.6 while completing this problem. Part A What energy change would accompany the loss of 0.1 mg in mass

The  energy change is  

Explanation:

   From the question we are told that

          Mass loss  is  

  Generally the energy change that  would accompany this loss  is mathematically represented as

Where  c is the speed of light with values

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

the dissolution of polymer can be thermodynamically described in 2 steps.
