Expert Answer:

Molarity of final mixture can be calculated by-
straight M equals fraction numerator straight M subscript 1 straight V subscript 1 plus straight M subscript 2 straight V subscript 2 over denominator straight V subscript 1 plus straight V subscript 2 end fraction
straight M equals fraction numerator 1.5 cross times 480 plus 520 cross times 1.2 over denominator 480 plus 520 end fraction
straight M equals fraction numerator 720 plus 624 over denominator 1000 end fraction
straight M equals 1344 over 1000 equals 1.344 space straight M
