a) nFe= \(\frac{5,6}{56}\)= 0,1 mol
nCu= \(\frac{64}{64}\)= 1mol
nAl= \(\frac{27}{27}\)= 1 mol
b)
nCO2= \(\frac{44}{12+16.2}\)= 1 mol
nH2= \(\frac{4}{1.2}\)= 2 mol
=> nhh= 1+2= 3 mol
Vhh= 3.22,4= 67,2 l
a) Số mol Fe trong 5,6 g Fe:
nFe=\(\frac{m_{Fe}}{M_{Fe}}=\frac{5,6}{56}=0,1\left(mol\right)\)
Số mol Cu có trong 64 g Cu:
nCu=\(\frac{m_{Cu}}{M_{Cu}}=\frac{64}{64}=1\left(mol\right)\)
Số mol Al có trong 27 g Al:
nAl= \(\frac{m_{Al}}{M_{Al}}=\frac{27}{27}=1\left(mol\right)\)
