2) 5 Ecuatii Chimice Cu Masa Molara
3) 4 Formule Chimice In Care Sa Folositi (r * a ,r * m ,c * p) (Ki)

Answer 1

O2   μ=2molOx16g/mol0 =32g/molO2;     HCl   μ=(1 +35,5)g/mol;
Na2O  μ=(2x23+16)g/mol;   KOH   μ   =(39+16+1)g/mol;     Ar   μ  =40g/mol
ZnSo4   μ= (65+32+4x16)g/mol;KNO3  μ=(39+14+3X18)g/mol;Ba0  μ=(137+16)g/m
NH3   μ=(14+3x1)g/mol;  NH4Cl    μ=(14+4x1+35,5)g/mol

HCl+NaOH= NaCl+H20;    2H2+O2=2H2O;       Zn+2HCl=ZnCl2+H2
C+O2=CO2    CaCO3= CaO+CO2    
 
 ν,moli= m,g /μ,g/mol  p,=(m,pur/m,impur)100  c%=(m,diz/m,sol)100
η= (m,practic/m,teoretic)/100
