a) nCaO=11,2/56=0,2(mol)
theo pthh : nCaCO3= nCaO=0,2(mol)
b) nCaO=7/56=0,125(mol)
theo pthh nCaCO3=nCaO=0,125(mol)
=> mCaCO3=0,125.100=12,5(g)
a)
nCaO=\(\dfrac{11,2}{56}=0,2\left(mol\right)\)
theo pthh: nCaO=nCaCO3=0,2(mol)
mCaCO3=0,2.100=20(g)
b)
nCaO=\(\dfrac{7}{56}=0,125\left(mol\right)\)
theo pthh: nCaO=nCaCO3=0,125(mol)
mCaCO3=0,125.100=12.5(g)
