a) + nNa = 11,5/23 = 0,5 (mol)
+ nO2 = 1,2/24 = 0,05 (mol)
b) + mMg = 0,6.24 = 14,4 (g)
+ nCO2 = \(\frac{1,8.10^{21}}{6.10^{23}}=0,003\left(mol\right)\)
c) VCO2 = 0,175.22,4 = 3,92 (l)
VH2 = 0,2.22,4 = 4,48 (l)
A) nNa= \(\frac{m_{Na}}{M_{Na}}=\frac{11,5}{23}=0,5\left(mol\right)\)
\(n_{O_2}=\frac{V_{O_2}}{24}=\frac{1,2}{24}=0,05\left(mol\right)\)
