Answer:

Moles of Na2co3 needed is 0.1875mol to react with h2so4.

Explanation:

Given Data:

   Molarity of h2so4= 0.250m

    volume of h2so4= 750ml

To Find:

      Moles of na2co3=?

Given:

                  As

           Moles = molarity x volume

For volume:

            volume = 750 mL x 1/1000 L

            volume = 0.750L

Putting values in mole formula ,

       Moles = 0.250M x 0.750L

       Moles = 0.250 mol/L x 0.750L

       Moles = 0.1875 mol

It is seen from the reaction that 1 mole of h2so4 reacts with just 1 mole of Na2co3.

Hence, 0.1875 mol of h2so4 will react with 0.1875mol of Na2co3.

so,

moles of Na2co3 needed is 0.1875mol.
