Problem with titration problem Please HELP!

Hi,

In our AS level chemistry coursework we have performed the following experiment.

We took 2.00g of MHCO3 where M stands for a group 1 metal.
We put it in 250ml volumetric flask and we produced our standard solution.

Then in a conical flask we put 25ml of MHCO3 and 4 drops of methyl orange indicator.
Using aqueous sulphuric acid of concentration 0.050 mol/dm3 we performed three titrations.
My mean titre value came out to be 25.225ml


Here are the questions I have to solve.

a) Calculate the amount (number of moles) of sulphuric acid in the mean titre.
b) Calculate the amount (number of moles) of MHCO3 in 25ml of solution X where X stands for the standard solution in the volumetric flask.
c) Calculate the concentration of MHCO3 in solution X in mol/dm3. Use this value to calculate the relative molecular mass of MHCO3 and then identify M.


Please help me and try to solve this for me as soon as possible. For any question put a reply on this forum or send me and e-mail to philip@philippos.net


Thanks
