d=M/M,H2---> M= 2X124,5g/mol= 249g/mol
Explicație:
niu,CO2= V/Vm= 2,24 l/22,4L/mol= 0,1mol---> 0,1molC
niu,H2O=m/M= 1,5g/18g/mol= 0,0833mol---> 0,167molH
niu,PbS=m/M= 7,968g/239g/mol=0,0333mol---> 0,0333molS
niu,AgCl=m/M= 4,784g/143,5g/mol= 0,0333mol----> 0,0333molCl
4,15g compus......0,1molC......0,167molH....0,0333molS.......0,0333molCl
249g(1mol).....................x.........................y...............................z..................t
x=6molC
y= 10molH
z= 2molS
t= 2molCl
formula chimica ar putea fi C5H10S2Cl2 cu M=217g/mol
DAR exista o diferenta de 32g pana la 249-g/mol--> compusul mai contine 2atO
C5H10S2Cl2O2
