Available are 1L of 0.1M NaCl and 2L of 0.2M CaCl_(2) solutions. Using only these two solutions what maximum volume of a solution can be prepared having [Cl^(-)]=0.34M exactly. Both electrolytes are strong

Answer»

`2.5L`
`2.4L`
`2.3L`
NONE of these

Solution :Let VOLUMES takne by `'x' & 'y'` litres, so (0.1x+0.4y)/(x+y)=0.34 & V_(g)=(x+y)` (to be MAXIMISED)
so `y=4x` so for maximum volome
`y=2L & x=(1)/(2)L`
