Find both the volume percent of a solution that has 10.0 g of ethanol (d = 0.7893 g/ml) and 90.0 g of water (d = 0.9987 g/ml). assume volumes are additive.

Answer:

Volume percent of a solution that has 10.0 g of ethanol= 12.37%

Volume percent of a solution that has 90.0 g of water = 87.69%

Explanation:

Volume Percent:

The volume percent helps us  to indicate the concentration of the solution when the volume of the solute and volume of the solution is given by

With respect to density 1mL of ethanol

=> 0.7893g or 10g of methanol contains

=>

=> 12.67mL

And for water =

=> 90.12mL

Now total volume = 90.12+ 12.67 = 102.79mL

%(v/v) for water =

 = 87.69%

%(v/v) for ethanol =

 = 12.37%

i think its 5049.

i hope this !
