peer agreement (net): +13weight/weight solution Explanation: weight/weight solution Solutions can be either w/w (weight to weight) or w/v (weight to volume). A percent solution consists of either "X" grams of compound in 100 grams of solute (w/w) or "X" grams of compound in 100 mls of solute (w/v). If the specific gravity of a w/w solution is known, a w/v ratio can be obtained by using the formula: specific gravity = wt/vol Reference: http://palimpsest.stanford.edu/waac/wn/wn12/wn12-3/wn12-306....
