250 mL of x M solution and 500 mL of y M solution of a solute A are mixed and diluted to 2 litre to produce a final concentration of 1.6 M.

Text Solution

Verified by Experts

We Know that,
`M_(1)V_(1)+M_(2)V_(2)=M_(R )(V_(1)+V_(2))`
`x xx 250+yxx500=1.6(2000)`
`x+2y=1.6xx8`
x+2y = 12.8
`(x)/(y)+2=(12.8)/(y)`
`(5)/(4)+2=(12.8)/(y)`
`(13)/(4)=(12.8)/(y)`
`y=(12.8xx4)/(13)=3.94`
Similary, `" " ` x=4.92
