  if  anybody  can help , please do
 
   i have a solution of H2SO4 , the molar concentration for H2SO4 is 0,02 mol/l
   the volume of this solution is 50ml and it's mixt with 450ml of H2O .

Calculate the final concentration (0.002) and use quadratic equation based on K2 of H2SO4
K2=(c+x)x/(c-x)
and calculate log from c+x
