a mixture of copper and copper oxide mass of 2 g acted with concentrated H2SO4.V (SO2) = 0.56 liters. Find the mass of Cuprum oxide.HELP ME,PLEASE!!

First you start by balancing the equation.
Cu + CuO + 2H_2SO_4 = 2CuSO_4 + H_2O + SO_2
Second you can use the molecular information to find out exactly what amount of what goes with what
2g = Cu + CuO
H2SO4. = 0.56L (I am guessing you mean pure liquid sulfuric acid)
1 Mole of Cu = 64g
1 Mole of CuO = 80g
1 Mole of H2SO4 = 98g
H2SO4 has a densityo of 1.84g/cm3
This means:
1 Mole of H2SO4 = 53.25mL
Can you take it from here?
