1.	Commercially available HCl contains 38% HCl by mass. Calculate it's molarity when it's density is 1.19g/ cm^3
Answer» Answer: answer is 21 ltr step-by-step EXPLANATION: let a=7x b=5x so, the mixture is 7x+5x=12x when, 9 LTRS DRAINED then 12x-9 then the can is filled with b(9x) so, atq 12x-9=9x 12x-9x=9 3x=9 x=3 so, a present initially =7*3=21 the answer is 21 litre.

Answer»

Answer:

answer is 21 ltr

step-by-step EXPLANATION:

let a=7x

b=5x

so, the mixture is 7x+5x=12x

when, 9 LTRS DRAINED then

12x-9

then the can is filled with b(9x)

so, atq

12x-9=9x

12x-9x=9

3x=9

x=3

so, a present initially =7*3=21

the answer is 21 litre.
