Question

a solution contains 40 ml of ethanol mixed with 100 ml of water
calculate the concentration in terms of volume by volume percentage
of the solution

na · Accepted Answer

Molecular mass of ethanol=46 g

Here we will take molecular mass of ethanol as the wt of solute
since ethanol is solute here

Percentage by volume of solute = (wt of
soluteÃ—100)/volume of solution

=46Ã—100/140 = 32 86%

a solution contains 40 ml of ethanol mixed with 100 ml of water .calculate the concentration in terms of volume by volume percentage of the solution
