What mass of electrons would be required to just neutralize the charge of 1.4 of protons?

**1.4 grams of protons

Look up the mass of one proton (and one electron).

mass proton x # protons = 1.4 grams. Solve for # protons.
#protons = # electrons.
# electrons x mass 1 electron = mass electrons.

It can be done another way with reasoning.
We know that a proton is about 1833x more massive than an electron; therefore, 1.4 g/1833 = about 0.00076g. See if you get that answer with the calculation above.

To find the mass of electrons required to neutralize the charge of 1.4 moles of protons, we first need to determine the number of electrons.

1 mole of protons contains Avogadro's number (6.022 × 10^23) protons. Therefore, 1.4 moles of protons would contain:

1.4 moles x (6.022 × 10^23 protons/mole) = 8.43 × 10^23 protons.

Since the number of protons is equal to the number of electrons required for neutrality, we need 8.43 × 10^23 electrons.

Now, to find the mass of electrons, we use the mass of a single electron, which is approximately 9.10938356 × 10^-31 kg.

Mass of electrons = Number of electrons x Mass of a single electron
Mass of electrons = (8.43 × 10^23 electrons) x (9.10938356 × 10^-31 kg/electron)
Mass of electrons = 7.691 × 10^-7 kg

Therefore, the mass of electrons required to neutralize the charge of 1.4 moles of protons is approximately 7.691 × 10^-7 kg.

To find the mass of electrons required to neutralize the charge of protons, we need to determine the number of electrons that can neutralize the charge of protons.

1. Start by finding the number of protons in 1.4 moles.
- We know that 1 mole of any substance contains 6.022 x 10^23 particles (Avogadro's number).
- Therefore, 1.4 moles will contain (1.4 x 6.022 x 10^23) protons.

2. Determine the total charge of these protons using the charge of a single proton.
- Each proton carries a charge of +1 elementary charge, which is equal to 1.6 x 10^(-19) Coulombs.
- Multiply the number of protons calculated in step 1 by the elementary charge to get the total charge.

3. Calculate the number of electrons needed to neutralize this charge.
- Since electrons carry a charge of -1 elementary charge, we can divide the total charge calculated in step 2 by the elementary charge to get the number of electrons required.
- Remember to take the absolute value of the result to ensure a positive number since we are dealing with magnitude.

4. Convert the number of electrons to mass.
- The mass of an electron is approximately 9.109 x 10^(-31) kilograms.
- Multiply the number of electrons calculated in step 3 by the mass of a single electron to get the mass required.

By following these steps, you can find the mass of electrons required to neutralize the charge of 1.4 moles of protons.
