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

Artist 52 [7]

<u>Answer:</u> The molarity of calcium hydroxide in the solution is 0.1 M

<u>Explanation:</u>

To calculate the concentration of base, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HBr

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is Ca(OH)_2

We are given:

n_1=1\\M_1=0.120M\\V_1=27.5mL\\n_2=2\\M_2=?M\\V_2=16.5mL

Putting values in above equation, we get:

1\times 0.120\times 27.5=2\times M_2\times 16.5\\\\M_2=0.1M

Hence, the molarity of Ca(OH)_2 in the solution is 0.1 M.

How can Newton's Third Law of Motion be used to explain why it is difficult to walk on a slippery surface, such as ice?
Olenka [21]
E ground pushes you forward. But that interaction is friction. Reduce friction and it doesn't matter how strong your legs are, the surface is incapable of pushing you accordingly. The coefficient of static friction is very low so it is easy to slide your foot rather than push.

Number of
babymother [125]

Answer:

A) 20

B) 40

C) Ca

D) 10

E) 9

F) F

Explanation:

The MASS NUMBER is the number of protons + the number of neutrons.

The ATOMIC NUMBER is the number of protons.

You can take the MASS NUMBER - ATOMIC NUMBER = NUMBER OF NEUTRONS.

Each element is unique and distinguished by the NUMBER OF PROTONS = ATOMIC NUMBER, ie...the number of protons in its nucleus. You can find the element's name and symbol on the Periodic Table.

2MG+O2 ...........2MGO
Galina-37 [17]
Mg + 1/2 O2 → MgO

1 mol = 24 g of Mg

X mol = 12 g of Mg

x = 0.5 moles of Mg

Mg :MgO = 1:1 (coefficient from equations using mole ratio)

So

0.5 moles of MgO

1 mol MgO = (24+16) g = 40 g

0.5 moles of MgO = 0.5 × 40

= 20 g of MgO produced
