No, the problem answer says this:
Knowing the amount of white phosphorus, the amount of phosphorus (V) oxide obtained is calculated according to the equation!
n P2O5=2*nP4=2⋅2mol=4mol , but i don't understand the logic behind this. This time the given number is that the white phosphorus is 2mol.

Calculate the amount of substance
P4+5O2→2P2O5.
I need to calculate what is the amount of 2P2O5 (and it is 4 mol)
The task says that there are 2mol of P4, so that means that i need 10mol of O2 for the reaction to happen, but how exactly do i predict that the amount of P2O5 is 4mol? What is the logic behind it?
