Question

Ex 1 va rog cat mai repede dau 25 pct.

Answer 1

se aplica relatiiile

N= niuxN,A   unde  niu= m/M ,   niu= V/Vm,     N,A= 6,023X10²³molec /mol

a.  N= 2N,A=....................

b. niu= 490000g/98g/mol= 5000mol----> N= 5000XN,A........

c.niu= 44,8 l /22,4 l/mol=2mol----> N=2XN,A=........

d.  niu=5000mol----> N=5000XN,A=..............

e. niu=73g/36,5g/mol= 2mol--------> N=2XN,A=........

f.  niu=224000 l/22,4 l/mol= 10000mol----> N= 10000XN,A=......
