Răspuns:
-calculez nr.moli CaCO3, stiind miu=100g/mol
niu= m/miu= 10000g/100g/mol=100mol
deduc moli CaO si CO2 din ecuatia chimica
1mol........................1mol........1mol
CaCO3-----------> CaO + CO2
100mol..........................x...................y
x=100molCaO
Y=100mol CO2
calculeze masele, stiind miu=44g/mol CO2 miu=56g/molCaO
m,CaO= 100molx56g/mol=5600g=5,6kg
m,CO2= 100molx44g/mol=4400g= 4.4kg
