Question

A solution 500ml of alcohol in water contain 250g of alcohol and water

​

Answer 1

Explanation:

This solution contains of this liquid solute (alcohol) mixed with a liquid solvent (water),so we have to calculate the concentration of this solution in terms of volume percentage of solute (alcohol). (Now, we know that :

Conentration of solution =Volume of soluteVolume of solution *100

Here ,Volume of solute (alcohol) =50mL

AND, Volume of solvent (water) =150mL

SO, Volume of solution = Volume Of

ANSWERAND, Volume of solvent (water) =150mL

SO, Volume of solution = Volume Of solute + Volume of Solvent

=50+150

=200mL

40 all 91

Now,putting these values of volume fo solute and volume of solution in the the above formula we get :

Concentration of sodium = 50200×100

=502

=25 per cent (by volume)

thus, the concentration of this alcohol solution is 25 per cent or that it is a 25% alcohol solution (by volume).
