If 450. ml of 6.0 m KBr solution is diluted to 900. ml, the concentration of the KBr solution is 3 M .
Calculation ,
Formula used : [tex]M_{1} V_{1} = M_{2} V_{2}[/tex]
Where M is the morality or concentration and V is the volume in ml .
Initial concentration ( [tex]M_{1}[/tex] ) = 6.0 M
Final concentration [tex]M_{2}[/tex] = ?
Initial volume ( [tex]V_{1}[/tex] ) = 450. ml
Final volume [tex]V_{2}[/tex] = 900. ml
Putting the value of Initial concentration , Initial volume and final volume in equation ( i ) we get .
6 × 450. ml = [tex]M_{2}[/tex] × 900. ml
[tex]M_{2}[/tex] = 6 × 450. ml / 900. ml = 3 M
