**Problem with titration problem Please HELP!!!**

Hi,

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

We took 2.00g of

**M**HCO3 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

**M**HCO3 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

**M**HCO3 in 25ml of solution

**X**where

**X**stands for the standard solution in the volumetric flask.

c) Calculate the concentration of

**M**HCO3 in solution X in mol/dm3. Use this value to calculate the relative molecular mass of

**M**HCO3 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
