Two solutions of a substances (non-electrolyte) are mixed in the manne

1.	Two solutions of a substances (non-electrolyte) are mixed in the manner, 480 mL of 1.5 M of first solution with 250 mL of 1.2 M of second solution.
Answer» 1.20 M 1.50 M 1.344 M 2.70 M SOLUTION :For solution l, millimoles `=MV =480xx1.5=720` For solution II,millimoles `=MV=520xx1.2=624` TOTAL millimoles `=720+624=1344` `THEREFORE` Molarity `=(1344)/(480+520)=1.344M`
