What is the weight ( in g) of Na_(2) CO_(3) molar mass = 106 ) present in 250 mL of Its 0.2 M solution ?

Assertion: In the titration of Na_(2)CO_(3) with HCl using methyl orange indicator, the volume of acid required is twice that of the acid required using phenolphthalein as indicaton. Reason: Two moles of HCl are required for the complete neutralisation of one mole of Na_(2)CO_(3) .
