Answer:

[tex]2.686*10^{24}[/tex]

Explanation:

Avogadro's number, 10 x 10^{23}, represens the number of atoms in a single mole of any substance.

Since we already of have the mole amount and don't need to calculate that from the grams of the substance, we can simply multiple Avogadro's number by the amount of moles given.

[tex]4.46 *(6.022*10^{23}) = 2.686 * 10^{24}[/tex]

The correct manipulation of the ideal gas equation as shown here is (PV)/R=nT.

According to the ideal gas law; PV = nRT. Now, this law applies to gases at high temperature and low pressure.

Given this fact, we know that the correct manipulation of the ideal gas equation as shown here is (PV)/R=nT.

Answer:

Gypsum and Selenite have the same chemical composition but differ in crystallisation habit. Selenite is usually crystalline and the association of the impurities is superficial which are eliminated by washing. Gypsum is fine grained in nature and is beneficiated by flotation only.

Based on the concentrations given, the volume of vinegar required is 5.04 mL.

The concentration of a solution is the amount of solute in a given volume of solution.

Concentration can be expressed as:

The concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.

Mass of vinegar = 4.76 g

molar mass if vinegar = 60 g/mol

moles of vinegar = 4.76/60 = 0.0793 moles

volume of solution/water = 100 mL or 0.1 L

Molarity of vinegar = 0.0793/0.1 = 0.793 M

1 mole of vinegar reacts with 1 mole of NaOH

let the volume of vinegar required be V

0.793 M × V = 40 × 0.1

V = 4/0.793

V = 5.04 mL

Therefore, the volume of vinegar require is 5.04 mL.

Sodium metal will conduct electricity in both a solid and liquid state, due to 'a sea' of delocalised electrons which can move and are able to carry charge

Sodium metal will conduct electricity only when it is in a liquid state or in solution because of the ionic state which are free to move in this state, allowing them to carry charge and conduct electricity.

The force of  friction acting on the block is -2N.

To find the force of a friction, the given datas are,

Force = 6N

Mass = 1 kg

Acceleration = 4 m/s².

The push or pull on an object that made the changes in the velocity with the mass. The object's or body's is to be at motion or at rest will be determined by Force. It has both the magnitude and direction.

The Net Force of the object can be written by:

Fnet = ma

where m is the mass of the object in kg

a is the acceleration of the object in m/s^2

Substituting the values in the formula,

Fnet = (1.0)(4.0)

        = 4 N

We also know that Net force is also the sum of all forces acting on an object. In this case Friction and the Pushing Force is acting on the object. Hence we can write that:

Fnet = Pushing Force + (-Friction)

6N = 4 N - Friction

Friction = - 2N

Hence the force of friction is -2 N.

Answer: 6.97 g

Explanation:

Grams of potassium sulfate must be added to make 200. mL of a 0.200 M potassium sulfate solution are 6.96.

Molarity of a given solution is known as the total number of moles of solute per litre of the solution.  A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

The unit of molarity is mol L⁻¹.

Molarity is temperature dependent because as temperature changes, volume of the solution also changes.

No. of moles of solute = 0.04

Mass of potassium sulfate = 174.2 × 0.04

Mass of potassium sulfate = 6.96 grams

Therefore, Grams of potassium sulfate must be added to make 200. mL of a 0.200 M potassium sulfate solution are 6.96.
