sodium metal dissolves im liquid mercury to form of NA(s) and Hg(l) are 0.97 g/ml and 13.6 g/ml respectively. a sodium amalgoum is made by dissolving 10 ml Na (s) in 20.0 ml Hg (l). The final volume of solution is 21.0 ml. Calculate the molarity of Na in the solution.
Convert volume Na to grams using density, then convert to mol. mol = grams/molar mass.
M Na = mols Na/total volume in L.
