1. n=2, T=290+273=563, V=122 cm³=0,122 dm³, R=0,082
pV=nRT => p*0,122=2*563*0,082=>
0,122p=92,332 /:0.122
=>p=756,81 atm
2. 1 mol Cl2.....17 protoni....17 electroni....18 neutroni
6 moli Cl2.......x protoni.....y electroni....z neutroni
X=6*17=102 protoni
Y=6*17=102 electroni
Z=6*18= 108 neutroni
1 mol O2...................32 g
n moli O2..................120 g
n=120/32=3,75 moli
1 mol O2...8 protoni....8 electroni...8 neutroni
3,75 moli O2......a protoni.....b electroni....c neutroni
a=b=c=3,75*8=30
Sper că te-am ajutat! succes!
