Is there some chart that will tell me, if there is 100 g of a 10% sucrose solution (w/v), what percent of that weight is sugar? For w/w it is easy, but I'm having trouble finding this information for w/v

And similarly for a 10% sucrose (w/v) and 20% ethanol (v/v) cocktail with both in the same solution... Is there some table that will tell me what the weight of the sucrose and the alcohol is in 100 g of this cocktail?

w/v concentration is in general problematic - in theory it is defined as [itex]\frac {m_{substance}} {v_{solution}}  \times 100\%[/itex], but it is quite common to misuse the definition and use v_solvent instead of the v_solution. Not that important for solutions of approximate concentration used in most of the recipes, but now and then it becomes a serious problem.

Tables for w/w can be converted to tables w/v, but it requires a density table. For solutions made of two components (like sugar/water, ethanol/water) this is usually not a problem, for multicomponent solutions you are probably out of luck.

Is there some chart that wZill tell me, if there is 100 g of a 10% sucrose solution (w/v), what percent of that weight is sugar?

What you need can be calculated with the ChemBuddy concentration calculator
