Approx. #380*g# of salt are produced....

Explanation:

We address the stoichiometric equation:

#Mg(s) + 2HCl(aq) rarr MgCl_2(aq) + H_2(g)uarr#

And if there are 8 moles of hydrogen chloride (or more likely #HCl(aq)#), stoichiometry demands a 4 mol quantity of metal, and a 4 mol quantity of salt product...

And so...#"mass of salt"=4*molxx95.21*g*mol^-1=??*g#

The obvious extension to this question to assess the VOLUME of dihydrogen gas evolved under standard conditions of temperature and pressure. So how about it?
