What volume of 0.305 m agno3 is required to react exactly with 155.0 ml of 0.274 m na2so4 solution? hint: you will want to write a balanced reaction?

The balanced chemical equation for reaction of and is as follows:

From the balanced chemical equation, 2 mol of reacts with 1 mol of  .

First calculating number of moles of as follows:

On rearranging,

Here, M is molarity and V is volume. The molarity of  is given 0.274 M or mol/L and volume 155 mL, putting the values,

Since, 1 mol of  reacts with 2 mol of   thus, number of moles of    will be .

Now, molarity of   is given 0.305 M or mol/L thus, volume can be calculated as follows:

Therefore, volume of   is 278.5 mL.
