dude exactly what I thought ! but the calculations never got me there ! :/
I see where u made the mistake. u found the concentration of fb4, while u were supposed to find the concentration of fb2, fb4 was diluted fb2.the conc. of fb4 multiplied by 10 was the concentration of fb2.

and what difference does it make to the value calculated by measuring cylinder rather than a burette

the percentage error would be higher due to lesser sensitivity of measuring cylinder, and there would be higher temperature rise so lesser percentage error in the reading for temperature rise.

yeah but question asked about accuracy? so I think one more sentence should have been added "LESS ACCURATE'
