The total negative charge on the electrons in 1mol of helium (atomic number 2, molar mass 4) is

The total negative charge on the electrons in 1 mol of helium is 2e⁻

The negative charge in 1 mole of a substance (here; it is helium atom) is equal to 6.022  10²³ atoms and it is also equal to 96485 C/mol

In 1 mole of helium containing 2 atomic numbers and a molar mass of 4.

The total negative charge on the electrons for 1 mole of helium can be computed as:

= 192970 C

Recall that:

The negative charge in 1 mole of helium = 96485 C/mol

∴

Numbers of negative charge in 192970 C of helium is:

= (192970/ 96485)

= 2e⁻

Explanation:

We are given that

Atomic number=2

We have to find the total negative charge on the electrons in one mole of Helium.

We know that atomic number=Proton number

Proton number=Number of electrons=2

Number of electrons in Helium=2

1 mole of Helium= atoms

We know that q=ne

Where n =Number of fundamental units

e=Charge on electron

1 e=

Using the formula

Total negative charge in 1 mole=

Hence, the total negative charge on the electrons in 1 mole of Helium=

im guessing the west of station b

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
