a) PTHH: Mg + H2SO4 \(\rightarrow\) MgSO4 + H2\(\uparrow\)
nMg = \(\frac{3,6}{24}=0,15\left(mol\right)\)
Theo PT: n\(H_2\) = nMg = 0,15 (mol)
=> V\(H_2\) = 0,15.22,4 = 3,36 (l)
b) Theo PT: n\(H_2SO_4\)= nMg = 0,15 (mol)
=> V\(H_2SO_4\) = \(\frac{0,15}{1,2}=0,125\left(l\right)=125\left(ml\right)\)
c) Theo PT: n\(MgSO_4\) = nMg = 0,15 (mol)
=> CM \(MgSO_4\) = \(\frac{0,15}{0,125}=1,2\left(M\right)\)
