The correct electron configuration of Phosphorus (P) :

1s², 2s², 2p⁶, 3s², 3p³ or [Ne] 3s²3p³

<h3>Further explanation</h3>

Given

Phosphorus (P) element

Required

The correct electron configuration

Solution

The electron configuration of an element is primarily based on the number of electrons

Phosphorus (symbol P) has the atomic number 15

The atomic number itself shows the number of electrons and the number of protons of an atom.

atomic number = number of electrons = number of protons in neutral atoms

So that the number of electrons from Phosphorus = 15

Its electron configuration  :

1s², 2s², 2p⁶, 3s², 3p³ or [Ne] 3s²3p³

chemical potential energy, thermal energy, electrical energy, sound energy

Explanation:

the coal is chemical potential energy because it is just sitting there, the coal fueled power plant is thermal energy because it is using the heat from the coal to work the power plant, that is then turned into electrical energy, which then goes to the radio which displays sound energy

Determine the molar mass of CuSO4 (the solute) in a 1.0M aqueous solution of CuSO4
inna [77]

Answer:

See explanation.

Explanation:

Hello,

In this case, we could have two possible solutions:

A) If you are asking for the molar mass, you should use the atomic mass of each element forming the compound, that is copper, sulfur and four times oxygen, so you can compute it as shown below:

M_{CuSO_4}=m_{Cu}+m_{S}+4*m_{O}=63.546 g/mol+32.00g/mol+4*16.00g/mol\\\\M_{CuSO_4}=159.546g/mol

That is the mass of copper (II) sulfate contained in 1 mol of substance.

B) On the other hand, if you need to compute the moles, forming a 1.0-M solution of copper (II) sulfate, you need the volume of the solution in litres as an additional data considering the formula of molarity:

M=\frac{n_{solute}}{V_{solution}}

So you can solve for the moles of the solute:

n_{solute}=M*V_{solution}

Nonetheless, we do not know the volume of the solution, so the moles of copper (II) sulfate could not be determined. Anyway, for an assumed volume of 1.5 L of solution, we could obtain:

n_{solute}=1mol/L*1.5L=1.5mol

But this is just a supposition.

Regards.
