Question

calculate the conncentration of a soultion in volume percent made when 56gram of water is mixed with 0.17 litre of enthanol (density of water is equal to 1.0 gram per cubic centimeter​

Answer 1

Answer:

Weight/ Volume of component =

Total volume of solution

Mass of component

×100

Mass of component i.e ethyl alcohol =40 g

Volume of water =50 ml

Volume of ethyl alcohol =

density

mass

=

0.8

40

=50 ml

Total volume of solution =Volume of H

2

O+Volume of ethyl alcohol

=50+50=100 ml

W/V of component =

100

40

×100=40%
