Avogadro constant is 6.02 1023 (the number of atoms or molecules per mole). What how much charge is there in 1 mole of electrons

? How much charge is there in 1 mole of hydrogen ions (H+). Remember that hydrogen consists of one electron and one proton, so hydrogen ions are just protons.

Answer:

Charge of 1 mole of electrons = -96488.46 C

Charge of 1 mole of protons/ hydrogen ions = +96488.46 C

Explanation:

Given, Avogadro constant:-

N_a=6.023\times 10^{23}

Thus, charge on 1 mole of electron can be calculated as:-

Charge on 1 electron = -1.602\times 10^{-19}\ C

Charge on 6.023\times 10^{23} electrons = -1.602\times 10^{-19}\times 6.023\times 10^{23}\ C = -96488.46 C

Charge of 1 mole of electrons = -96488.46 C

Charge of electron = Charge on proton (magnitude), Only the charge is different. Electron has negative charge and protons have positive charge.

Charge of 1 mole of protons/ hydrogen ions = +96488.46 C

Verdich [7]

<u>Answer:</u>

<u>For 1:</u> The correct answer is Option A.

<u>For 2:</u> The correct answer is Option B.

<u>For 3:</u> The correct answer is Option C.

<u>Explanation:</u>

<u>For 1:</u>

Atomic number is defined as the number of electrons or number of protons that are present in a neutral atom. It is represented as Z.

Z = Atomic number = Number of electrons = Number of protons

Mass number is defined as the sum of number of protons and number of neutrons present in an atom. It is represented as A.

A = Mass number = Number of protons + Number of neutrons

Hence, the correct answer is Option A.

  • <u>For 2:</u>

The isotopic representation of an atom is: _Z^A\textrm{X}

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

We are given:

An isotopic representation of beryllium atom:  _4^9\textrm{Be}

Thus, the number '4' represents the atomic number of beryllium, number '9' represents the mass number of beryllium atom.

Hence, the correct answer is Option B.

  • <u>For 3:</u>

In CO compound:

Mass of oxygen = 16 g

Mass of carbon = 12 g

In CO_2 compound:

Mass of oxygen = 32 g

Mass of carbon = 12 g

Thus, the ratio of mass of oxygen in CO_2 and CO is:

CO_2:CO=32:16=2:1

Hence, the correct answer is Option C.
