Question

ten litres of water is added to 50 litres of a solution containing 20 percent of alcohol in water. what is the concentration of alcohol in tha solution now? ​

Answer 1

Step-by-step explanation:

According to the dilution law,

C_1V_1=C_2V_2C

1

V

1

=C

2

V

2

where,

C_1C

1

= concentration of pure solution = 20 %

V_1V

1

= volume of pure acid solution = 50 L

C_2C

2

= concentration of diluted solution= ?

V_2V

2

= volume of diluted solution= (50+10)L = 60 L

20\times 50=C_2\times 6020×50=C

2

×60

C_2=16.7C

2

=16.7

Thus the strength of alcohol in the solution now is 16.7 %
