Answer 1

Answer:

Answer:

$\bigstar\:{\underline{\frak{Given :-}}}$

When 5.00 g of HCl are combîned with an excéss of Mg(OH)₂.

$\bigstar\:{\underline{\frak{Find\: Out :-}}}$

What mass of MgCl₂ can be produced?

$\bigstar\:{\underline{\frak{Solution :-}}}$

Magnesium hydroxide Mg(OH)₂, as "Milk of Magnesia" can be used to neutralize excess stomach acid, represented by HCl(aq) :

$\bullet\:{\underline{\bf{Mg(OH)_2(s) + 2HCl\: (aq) \rightarrow\: MgCl_2\:(aq) + 2H_2O(l)}}}$

☣ Moles of HCl :-

We have :

Mass = 5.00 g

Molar Mass = 36.5 g/mol

➙ $\red{ \boxed{\sf{Moles =\: \dfrac{Given\: Mass}{Molar\: Mass}}}}$

➙ Mole = $\sf \dfrac{5.00}{36.5}$

➙ ${\small{\bold{\purple{\underline{Mole =\: 0.137\: Moles}}}}}$

☣ Mass of MgCl₂ can be produced :-

We have :

Number of Moles = 0.0685 Mole

Mass = 58 g/mol

$\red{ \boxed{\sf{Mass =\: Number\: of\: Moles \times Molar\: Mass}}}$

➔ $\sf Mass =\: 0.0685 \times 58$

➔ ${\small{\bold{\green{\underline{Mass =\: 3.973\: g}}}}}$

Henceforth, the mass of MgCl₂ can be produced is 3.973 g.

Magnesium hydroxide :-

Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH)₂.

It occurs in nature as the mineral brucite. It is a white solid with low solubility in water.

Molar Mass :

Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol.

The units of molar mass are grams per mole, abbreviated as g/mol.
