Answer 1

Answer:

hmmmmmmmmm

Explanation:

Mg+2HCl→MgCl  

2

​  

+H  

2

​  

 

1 mol of Mg is consumed when 1 mol of H  

2

​  

 is produced.

So, 4.2×10  

−3

 mol of Mg is consumed when 4.2×10  

−3

 mol of H  

2

​  

 is produced.

Mass of Mg consumed =n×M=4.2×10  

−3

×24=0.1 g.

Answer 2

Answer:

Explanation:

Mg+2HCl→MgCl2 +H2

1 mole of Mg is consumed when 1 mole of H2  is produced.

So, 4.2×10−3  mole of Mg is consumed when 4.2×10−3  mole of H2  is produced.

Mass of Mg consumed =n×M=4.2×10−3 ×24=0.1 g.
