Question

a solution contains 5 ml of alcohol in 70 ml of water
calculate the volume by Volumes by Solution ​

Answer 1

Explanation:

23-Jul-2016 — Volume of solvent x 100% volume of solvent= 5ml · volume of solution volume of solution= 5 + 70 ml = 75ml · %volume= 5ml x 100 = 20/3 = 6.67%.

Answer 2

Answer:

Explanation:

we know that volume percentage=

(volume of one component/total volume of the solution )*100

volume of the solution=75ml

so volume percentage=5/75*100=6.67%

(note that there is no conservation of volume like the conservation of mass.

For example,when we say 20% methanol,we mean 20ml ethanol dissolved in enough water so that the final volume becomes 100ml.)

hope this helps you

thank you
