Zn+H2SO4=ZnSO4+H2
50g
molar mass of ZnSO4=161.47g
moles of ZnSO4=given gm mass/molar mass
=50/161.47
=0.3(approx.)
according to equation ,
one mole of Zn reacts with one mole of H2SO4 to give one mole of ZnSO4 and one mole of H2
therefore moles of Zn= 0.3
mass of Zn= moles*molar mass
= 0.3 *65.38
= 19.616g
