\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

\longrightarrow \sf{Mg+2HCI \Longrightarrow MgCl_2+H_2}

\longrightarrow \sf{molMg=129gMg \times \dfrac{1molMg}{24.305gMg=} }

\small \sf{\longrightarrow molH_2=7.90molMg \times \dfrac{1molH_2}{1molMg}= 7.90molH_2 }

\small \sf{\longrightarrow massH_2=7.90H_2 \times \dfrac{2.016g}{1molH_2}= 7.90molH_2= 15.9 \: gH_2}
