Answer:

<h2>1.8 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 3 cm³

density = 0.6 g/cm³

We have

mass = 0.6 × 3 = 1.8

We have the final answer as

<h3>1.8 g</h3>

Neporo4naja [7]

The solution could be described like a saturated and concentrated solution.

<h3>Solutions</h3>

Dissolution of solutions can occur in certain ways. These ways depend on the solvent dilution coefficient and the amount of solute.

If the amount of solute is less than the solvent can dissolve, the solution is unsaturated.

If the amount of solute is exactly the same, the solution is saturated.

If the amount is greater, the solution is supersaturated.

So, since the amount of solute is exactly equal to the amount that the solvent can dissolve, the solution is saturated and concentrated.

Explanation:

For aluminum phosphate AlPO4 (s) <------> Al^3+(aq) + PO4^3-(aq)

Ksp= [Al^3+] [PO4^3-]

For magnesium hydroxide

Mg(OH)2(s) <--------> Mg^2+(aq) +. 2OH^-(aq)

Ksp= [Mg2+] [2OH^-]^2

What is the pressure of a mixture of nitrogen (N2) and oxygen (O2) if partial pressure of N2 is 594 mm Hg and the partial pressu
ipn [44]

Answer:

Total pressure = 759 mmHg

Explanation:

Given data:

Partial pressure of oxygen = 165 mmHg

Partial pressure of nitrogen = 594 mmHg

Total pressure = ?

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Total pressure = P(O₂) +  P(N₂)

Total pressure =  165 mmHg + 594 mmHg

Total pressure = 759 mmHg

The volume density of atoms for a bcc lattice is 5 x 1026 m-3. Assume that the atoms are hard spheres with each atom touching it
ollegr [7]

Explanation:

It is known that for a body centered cubic unit cell there are 2 atoms per unit cell.

This means that volume occupied by 2 atoms is equal to volume of the unit cell.

So, according to the volume density

        5 \times 10^{26} atoms = 1 [tex]m^{3}

        2 atoms = \frac{1 m^{3}}{5 \times 10^{26} atoms} \times 2 atoms

                     = 4 \times 10^{-27} m^{3}

Formula for volume of a cube is a^{3}. Therefore,

           Volume of the cube = 4 \times 10^{-27} m^{3}

As lattice constant (a) = (4 \times 10^{-27} m^{3})^{\frac{1}{3}}

                                   = 1.59 \times 10^{-9} m

Therefore, the value of lattice constant is 1.59 \times 10^{-9} m.

And, for bcc unit cell the value of radius is as follows.

                 r = \frac{\sqrt{3}}{4}a

Hence, effective radius of the atom is calculated as follows.

                 r = \frac{\sqrt{3}}{4}a

                   = \frac{\sqrt{3}}{4} \times 1.59 \times 10^{-9} m

                   = 6.9 \times 10^{-10} m

Hence, the value of effective radius of the atom is 6.9 \times 10^{-10} m.
