MCO2=AC+2AO=12+2*16=44g/mol
n=m/M=88/44=2 moli CO2
nr moli total = 2+3=5 moli amestec (CO2+CO)
%CO2=nCO2/n amestec*100 = 2/5*100 = Calculeaza !!
%CO=nCO/n amestec*100 =3/5*100 = Calculeaza !!
b) 1 mol CO2...........................NA=6,023*10^23 molecule
2 moli CO2...............................x= Calculeaza !!
1 mol CO.........................6,023*10^23 molecule
3 moli CO........................x= Calculeaza !!
c) 5 moli amestec....................=5*6,023*10^23 electroni
la c) nu sunt sigur ca asa se face,,
