MOLES TO MASS: Mg + 2 HCl ➞ MgCl2 + H2
2.26 moles of HCl are reacted how many grams of Mg were used in the reaction??

Answer 1

The balanced chemical equation is:

Mg + 2 HCl ➞ MgCl2 + H2

From the equation, we see that 1 mole of Mg reacts with 2 moles of HCl. So, to determine how many moles of Mg reacted with 2.26 moles of HCl, we divide 2.26 moles by 2:

2.26 moles HCl / 2 = 1.13 moles Mg

Now we can use the molar mass of Mg to convert moles of Mg to grams:

1.13 moles Mg x 24.31 g/mol = 27.49 grams Mg

Therefore, if 2.26 moles of HCl were reacted, then 27.49 grams of Mg were used in the reaction.

I Hope This Helps!
