How many grams of MgCl are formed when 7.2 magnesium oxide reacts with hydrochloric acid?
| March 23, 2021 | education
Magnesium chloride formation reaction:
MgO + 2HCl = MgCl2 + H2O.
Let’s calculate the amount of moles of magnesium oxide.
n (MgO) = m / Mr = 7.2 / 40 = 0.18 mol.
The amount of magnesium oxide and chloride will be equal.
n (MgO) = n (MgCl2).
The mass of the salt is.
m (MgCl2) = n • Mr = 0.18 • 95 = 17.1 g.
