At 25 °C, an aqueous solution has an equilibrium concentration of 0.00253 M for a generic cation, A2+(aq), and 0.00506 M for a g
aleksandrvk [35]

Answer:

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M

Explanation:

Step 1: The balanced equation

AB2 ⇒ A2+ + 2B-

Step 2: Given data

Concentration of A2+ = 0.00253 M

Concentration of B- = 0.00506 M

Step 3: Calculate the equilibrium constant

Equilibrium constant Ksp of [AB2] = [A2+][B-]²

Ksp = 0.00253 * 0.00506² = 6.4777 *10^-8 M

The equilibrium constant Ksp of the generic salt AB2 =  6.4777 *10^-8 M

Which of the following steps correctly converts 3 moles of fluorine to an equivalent number of particles of fluorine? Divide Avo
Eva8 [605]

Answer:

Multiply 3 by Avogadro's number.

Explanation:

The mole can be defined as the amount of a substance that contains Avogadro’s number of particles, 6.02 x 10²³.

For elementary particles:

Number of particles=

number of moles x 6.02 x10²³

From the question,

Number of moles = 3moles

Number of particles = 3 x 6.02 x10²³

How many molecules of oxygen are there in 1.00 dm3 of oxygen at standard pressure and a temperature of 273 K. Give your answer t
rewona [7]
  • Pressure=p=1atm
  • Temperature=T=273K.
  • V=1dm^3=1L

we need no of moles

\\ \tt\hookrightarrow PV=nRT

\\ \tt\hookrightarrow n=\dfrac{PV}{RT}

\\ \tt\hookrightarrow n=\dfrac{1}{273(8.314)}

\\ \tt\hookrightarrow n=1/2269.7=0.0004mol

No of molecules=No of moles×Avagadro no

\\ \tt\hookrightarrow 0.0004(6.023\times 10^{23})

\\ \tt\hookrightarrow 2.4\times 10^{20} molecules
