Lets assume that the acid is HCL
Reaction process;Mg+2HCL→MgCl2+H2
This shows that 1 mole of Mg will produce=1mole of hydrogen
Thus,12g of Mg will produce=1mole of hydrogen ×12g÷24g=0.5moles of hydrogen.
When the dibasic acid like H2SO4
The reaction will be:
Mg+H2SO4→MgSO4+H2
Hence 1mole of Mg will produce 1 mole of hydrogen.
