Many thanks. I tried to look up specific gravity in my textbook (I'm in Freshman Inorganic chemistry) and it's not there so I guess I'm not supposed to know that yet.
What I'm trying to do is find the work done when 50 grams of tin dissolves in excess acid at 1 atm and 25 C. I know that work=-(P)(deltaV). In similar problems in the chapter, when we didn't know volume, we calculated it using V=nRT/P. However, in all those problems, the products & reactants were liquids and/or gasses with mass given in liters. For this problem, the initial volume is given in grams. I'm assuming I should use the same approach, i.e. calculate V-final and V-initial, determine delta V, and solve.
Would anyone be willing to comment on whether or not this is the right approach?
