There is no way to know which reaction requires which catalyst. However, if you apply copper to a reaction where it does act as a catalyst, the rate of reaction will be much faster as it lowers the activation energy for successful collisions.
24
Explanation:
we have the equation d = m/v so here the density is 12 and the volume is 2, 12 = m/2. in this situation we multiply 12×2= 24. The mass is 24.
Let's check if it works with the formula
24/2 = 12
12 = 24/2
yes. it works
the answer is mass = 24
