Magnesium reacts with hydrochloric acid to produce magnesium chloride.

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

What mass of magnesium chloride is produced when 12 g of magnesium reacts completely with excess hydrochloric acid?

Ar values:
Cl = 35.5
O = 16
H = 1
Ca = 40
C = 12
Mg = 24
Cu = 63.5
N = 14


A: 95 g

B: 35.5 g

C: 24 g

D: 47.5 g
