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.
