O is a dibasic acid H2X .G is a solution containing 1.00g of NaOH in 250cm³ solution.

1) calculate the concentration of G in mol/dm³
2) calculate the concentration of O in mol /dm³
3) molar mass of acid given that 100cm³ of O contains 0.485g of the acid
Please I need all your help with the solution I'm really stuck

See your other post. You just don't have enough information to get moles and without moles you can't do molar mass or moles/dm^3. In problems like this usually there is a statement about so many cc of G react with so many cc of O but I don't see anything like that in either post.
