Dear Student,â€‹

M1V1+M2V2=M3(V1+V2)or, a×500+b×250=M3(500+250)or, 500 a+ 250 b= 750 M3     
(i)and, M3(V1+V2) = M4V4or, 750M3=1
6×2000or M3=4
26MTherefore, 500 a+250 b=750×4
26 =3200or, 50a + 25b=320Dividing by b, we get50ab+25=320ba:b=2:5or, 50×25+25=320bor, b=7
11and  50a + 25×7
11=320or, 50 a=320-177 77or, a=2 84

500 ml of aM solution and 250ml of bM solution of the same solute are mixed and diluted to 2L.The diluted solution shows the molarity 1.6m.If a:b is 2:5 then calculate a and b.
