hello

I am doing my A2 chemistry course work in investigating glucose content in pamogranet juice which is made in super market and the one we make at home.
and we are trying to find out which type of juice have higher percentage or gulcose.
we used titration to do the experiment.
i have attached the the results.
also i have find out that the juice from market has got 16.5% of gluocose and the juice made in the lab has got 9.9%.
i have done the calculation but i m not sure if i have done it right.
the mass of pamogranate is 100g.

i hope tat helps you.
