The concentration of Hydrogen chloride in g per dm³ = 64 g/dm³

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent

A solution of hydrochloric acid contains 3.2 g of hydrogen chloride in 50 cm³, so the concentration :

\tt =\dfrac{3.2~g}{50~cm^3}=0.064~g/cm^3

For the concentration of Hydrogen chloride in g per dm³ :

\tt =0.064\dfrac{g}{cm^3}\times \dfrac{1000~cm^3}{dm^3}\\\\=64~g/dm^3

How many moles of glucose (C6H12O6) are in 1.5 liters of a 4.5 M C6H12O6 solution?
Lana71 [14]
If M is the molar concentration of C_6H_{12}O_6, n is the number of moles and V is the volume of the solution:

M=\dfrac{n}{V}\Longrightarrow 4.5=\dfrac{n}{1.5}\iff n=4.5\times1.5\iff \boxed{n=6.75~moles}\\\\6.75\approx6.8\Longrightarrow Answer~C

Answer:

Amount of toxic Ba²+ ingested by the patient = 0.404 mg

Explanation:

The solubility product constant, Ksp for barium sulfate is 1.1 x 10-¹⁰.

Considering the dissociation products of aqueous BaSO₄ solution:

BaSO₄ (aq) ⇄ Ba²+ (aq) + SO₄²- (aq)

Let the concentration of Ba²+ be x and that of SO₄²- be x as well since the mole ratio of the products is 1 : 1

Ksp = [Ba²+] × [SO₄²-]

Ksp = x × x = x²

x² = 1.1 x 10-¹⁰

x = 1.05 × 10-⁵ M

Therefore, the concentration of Ba²+ ions = 1.05 × 10-⁵ M

Volume of saturated barium sulfate ingested by the patient = 280 mL = 0.280 L

Number of moles of Ba²+ ions = molar concentration × volume

Number of moles of Ba²+ = 1.05 × 10-⁵ M × 0.280 L = 2.94 × 10-⁶ moles

Mass of Ba²+ ions = number of moles × molar mass

Molar mass of Ba²+ = 137.33 g/mol

Mass of Ba²+ = 2.94 × 10-⁶ moles × 137.33 g/mol = 4.04 × 10-⁴ g = 0.404 mg

Therefore, amount of toxic Ba²+ ingested by the patient = 0.404 mg
