Question

intr-un recipient se gasesc 8 moli de azot iar in altu se gasesc 4,8184*10 la puterea24 molecule pde hidrogen . in care recipient din cele doua recipiente se gaseste o masa mai mare de gaz ?

Answer 1

uTILIZEZ RELATIILE:  m=n,molixMg/mol,      M-masa molara
                                      n= N/N,Avogadro        N,A= 6,023X110²³

m,N2= 8molx28g/mol=

n= 4,8148x10²³/ 6,023x10²³= 8mol
m,H2= 8molx2g/mol
COMPARA CELE DOUA MASE !!!!!
