Answer:

2 L

Explanation:

Divide the mass by the concentration to find the volume.

(6 g)/(3g/L) = 2 L

According to the concept of solubility, in order to make solution of sugar the total volume of solution is 2 g/L.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

In order to calculate total volume of solution divide mass/ concentration that is 6/3=2 g/L.

Thus, the total volume of the solution is 2 g/L.

Answer:

pH = 6.20

Explanation:

The pKa of cacodylic acid is 6.

To solve this question we must use Henderson-Hasselbalch equation:

pH = pKa +log [A⁻] / [HA]

Where pKa is the pKa of the weak acid = 6

And [] could be taken as the moles of A⁻ the conjugate base, and HA, the weak acid.

The moles of the NaOH added to the solution of the weak acid are = Moles A⁻

And moles HA = Initial moles HA - Moles NaOH added

Initial moles HA:

0.0200L * (0.130mol / L) = 0.00260 moles

Moles NaOH:

0.0200L * (0.0800mol / L) = 0.00160 moles = [A⁻]

Moles HA =

0.00260 moles - 0.00160 moles = 0.00100 moles = [HA]

pH = 6 +log [0.00160 moles] / [0.00100 moles]

The pH of the resulting solution is 1.6.

Let cacodylic acid be HA, mixing cacodylic acid and NaOH, the following occurs;

HA(aq) + NaOH(aq) ------> NaA(aq) + H2O(l)

Number of moles of NaOH = 0.0800 molL−1 × 20.0/1000 = 0.0016 moles

Number of moles of HA = 20.0/1000  × 0.130 = 0.0026 moles

We can see that the HA is in excess, Number of moles of excess acid =

0.0026 - 0.0016 = 0.001 moles

Total volume of solution = 20.0 mL + 20.0 mL = 40 mL or 0.004 L

Molarity of excess acid =  0.001 moles/0.004 L = 0.025 M

pH = -log[H^+]

pH = -log[0.025 M]

pH = 1.6

Answer:

22.4 L

Explanation:

A gas at STP will possess the following;

Pressure (P) = 1 atm

Temperature (T) = 273K

General gas constant (R) = 0.0821 Latm/molK

Using the general gas law formula to calculate the volume a gas of 1 mol will contain;

PV = nRT

V = nRT/P

V = 1 × 0.0821 × 273 ÷ 1

V = 22.41/1

V = 22.4 litres

Explanation:

4 Al + 3 O₂ → 2 Al₂O₃

First, we convert 6 moles of aluminum (Al) into moles of aluminum oxide (Al₂O₃), using the stoichiometric coefficients:

6 mol Al * [tex]\frac{2molAl_2O_3}{4molAl}[/tex] = 3 mol Al₂O₃

Finally we convert 3 moles of aluminum oxide into grams, using its molar mass:

3 mol Al₂O₃ * 101.96 g/mol = 305.88 g

Answer:

Change in heat (Q) = -1.7316 x 10⁴

Explanation:

Given:

Mass m = 38.68 g

Change in temperature Δt = (197-304) = -107°C

Specific heat C = 4.184 J/g°C

Find:

Change in heat (Q)

Computation:

Change in heat (Q) = (C)(m)(Δt)

Change in heat (Q) = (4.184)(38.68)(-107)

Change in heat (Q) = -1.7316 x 10⁴
