where  and  are initial and final concentration respectively.  and  are initial and final volume respectively.

Here  = ,  = 1.00 mL,  = 10.00 mL

So,  =  

So, concentration of solution A =  

Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL

Similarly as above,  =  

So, concentration of solution B =
