										Hi..
You can assume that the mass of Na2CO3 in the mixture is x g.
So, one can easily calculate the no. of moles of the two substances i.e, both the Na2CO3 and Na2SO4 in the 10 mL of the mixture.
Given that on neutralization of this solution, one requires NH2SO4 which is gonna react with Na2CO3, so the no. of moles of Na2CO3 that are required to react with the given no. of moles of NH2SO4 can thus be calculated using the balanced chemical equation.
Try solving the question using the above hints.
