What mass of sulfuric acid is required to interact with copper oxide (3) weighing 8 grams

The interaction of copper (III) oxide and sulfuric acid is as follows:
Cu2O3 + 3H2SO4 = Cu2 (SO4) 3 + 3H2O.
The reaction enters 8/176 = 0.045 mol of Cu2O3, and 3 times more H2SO4. The mass of the latter is 0.136 * 98 = 13.36 g.
