<span>When compounds like salt dissolve the atoms basically float around with the water. When they are a solid powder all the molecules sit closely packed together but when you dissolve it, they can all separate and float around with the water. </span>

If the OH‑ ion concentration in an aqueous solution at 25.0 °C is 6.6 x 10‑4 M, what is the molarity of the H+ ion?

Tresset [83]

Answer:

1.5 × 10⁻¹¹ M

Explanation:

Step 1: Given data

Concentration of OH⁻ ([OH⁻]): 6.6 × 10⁻⁴ M

Temperature: 25°C

Concentration of H⁺ ([H⁺]): ?

Step 2: Consider the self-ionization of water

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Step 3: Calculate the molar concentration of H⁺

We will use the equilibrium constant for the self-ionization of water (Kw).

Kw = 1.0 × 10⁻¹⁴ = [H⁺] × [OH⁻]

[H⁺] = 1.0 × 10⁻¹⁴ / [OH⁻]

[H⁺] = 1.0 × 10⁻¹⁴ / 6.6 × 10⁻⁴

[H⁺] = 1.5 × 10⁻¹¹ M

Calculate the molecular mass of the nonionic solutes.

3241004551 [841]

Answer:

The molecular mass of the nonionic solutes is 124,90 g/m

Explanation:

This is the formula for boiling point elevation.

ΔT = Kb . m

Where ΔT = Tb (solution) - Tb (pure solvent)

Where Kb = the ebullioscopic constant

Where m = molality (moles of solute in 1kg of solvent)

Kb for water is 0,512°C/molal

100,680°C - 100°C = 0,512°C/molal . m

0,680°C = 0,512°C/molal . m

0,680°C /0,512 molal/°C = m

1,32 molality (This are my solute moles in 1kg (1000g) of solvent but I have just 390 g, so let's build the rule of three)

1000 g _____ 1,32 moles

390 g ______ (3,90 g . 1,32 moles) / 1000 g = 0,5148 moles

Molecular mass = g/ mol (mass/moles)

64,3 g /0,5148 moles = 124,90 g/m

What is the concentration, in millimolar, of a 1 mg/ml solution of NaCl (molecular weight = 58 Da)?

sineoko [7]

Explanation:

Relation between molarity and molar mass is as follows.

Molarity = $\frac{mass}{\text{molar mass}} \times \frac{1000}{V (in ml)}$
