(x cc)*(.92 g/cc) = 5000 g (write an equation for the problem)
x cc = (5000 g)/(.92 g/cc) (solve the equation for the unknown)
x cc = (5000/.92) cc = 5434.8 cc
Since the density is given to 2 significant figures, and the weight is given to an undetermined number of significant figures (perhaps only 1), the proper answer to this question is 5400 cc, that is, rounded to 2 significant figures.
