300ml=0,3(lít)
\(n_{H_2SO_4}=C_M.V_{dd}=1.0,3=0,3\left(mol\right)\)
a)\(Mg+H_2SO_4\rightarrow MgSO_4+H_2\)
1...............1................1.................1(mol)
0,3..........0,3..............0,3...............0,3(mol)
b)\(m_{Mg}=n.M=0,3.24=7,2\left(g\right)\)
c)\(V_{H_2}=n.22,4=0,3.22,4=6,72\left(l\right)\)
d)\(V_{dd}=0,3\left(l\right)\)
\(C_{M\left(MgSO_4\right)}=\dfrac{n}{V_{dd}}=\dfrac{0,3}{0,3}=1M\)
Câu d mình ko biết đúg ko nha.
