-calculez moli Al : niu= 8,1g/ 27g/mol=3mol Al
2mol 6mol 3mol
-2Al + 6HCl ---> 2AlCl3 + 3H2↑
3mol niu=9mol niu=4,5mol
m,HCl= 9molx36,5g/mol= 328,5gacid -reprezinta md din solutie
c/100= md/ms--> 36,5/100= 328,5/ms CALCULEAZA ms!!!!
V₀= 4,5molx22,4l/mol= 100,8 l
p₀V₀/ T₀= pxV/ T---. >V=p₀V₀ T/pT₀
p= 765/760 at, deoarece 1 at=760mmHg
T=27+273=300 K
V= 1 X100,8X300/ 1,0065X273 calculeaza V !!!!!!!!
