I don't know,but just wasn't a little longer to get an answer
Here amount of HCl can be calculated as:
As concentration of HCl= 1 M or 1 mol L
Volume of HCl= 75mL=0.075L
So number of moles of HCl will be= 0.075\times 1
number of moles of HCl will be= 0.075 mol
As we see from the equation,
Mg (s) + 2HCl (aq)------->H₂ (g) + MgCl₂ (aq)
That 2 moles of HCl will produce 1 mole of H₂
So 0.075 mol of HCl will produce 0.038 mole of H₂
