Answer:

12.64 cm^3 to the nearest hundredth

Explanation:

1 L of 0.25M of HCl contains 0.25 * (1.008 * 35.45) g of HCl

= 9.1145 g HCl.

So 2 litres contain 18.229 g HCl.

So we need the volume of concentrated acid which contains 18.229 g HCl.

1.46 * 0.98 = 1.4308 g are in  1 cm^3

So 18.229 g are in  18.229/1.4308

= 12.6404 cm^3 (answer).
