the first titration gives u the y intercept of the sketch graph....
the second one gives u another point on the line with the coordinates (12, titre in (b))

Use these points to calculate the gradient of the line and then use the gradient to find the x intercept of the line...this is the volume that reacts with all of the Fe2 positive ions..
