\(n_{MgSO_4}=0,1.2=0,2\left(mol\right)\)
a. \(2KOH+MgSO_4\rightarrow Mg\left(OH\right)_2+K_2SO_4\)
\(Mg\left(OH\right)_2\underrightarrow{t^o}MgO+H_2O\)
b. có: \(n_{KOH}=2n_{MgSO_4}=2.0,2=0,4\left(mol\right)\)
=> \(m_{bazo.tham.gia}=0,4.56=22,4\left(g\right)\)
c. rắn thu được sau khi nung: MgO
có: \(n_{MgO}=n_{Mg\left(OH\right)_2}=n_{MgSO_4}=0,2\left(mol\right)\)
=> \(m_{rắn}=m_{MgO}=0,2.40=8\left(g\right)\)
