What mass of protons would be required to just neutralize the charge of 1.1 g of electrons?

9.11E-28 g/e x #e = 1.1g

Solve for #e.
Since charge on e is same as charge on p(except for opposite sign), the number of p = number e.
Then #protons x mass/proton = total mass protons.

To determine the mass of protons required to neutralize the charge of electrons, we need to consider the charge of each species and the quantity of electrons given.

1. Calculate the number of electrons:
- From the given mass of electrons (1.1 g), we can use the molar mass of electrons to convert to moles.
- The molar mass of electrons is the same as the molar mass of hydrogen (H), which is 1 g/mol.
- Therefore, the number of moles of electrons can be calculated as follows:
Number of moles (electrons) = mass (electrons) / molar mass (electrons)
= 1.1 g / 1 g/mol
= 1.1 mol

2. Calculate the total charge of the given electrons:
- Each electron carries a unit negative charge (e^-).
- Therefore, the total charge (Q) of the given electrons can be calculated by multiplying the number of electrons by the magnitude of the charge (e):
Q = number of electrons × charge of each electron
= 1.1 mol × 6.022 × 10^23 electrons/mol × 1.602 × 10^-19 C/electron
≈ 1.05 × 10^5 C

3. Determine the mass of protons equivalent to this charge:
- Since a proton carries a unit positive charge (e^+), the mass of protons required to neutralize the given charge can be determined by equating their charges:

Q (protons) = Q (electrons)
mass (protons) × (charge of each proton) = charge of electrons

- Rearranging the equation to solve for mass(protons):

mass (protons) = (charge of electrons) / (charge of each proton)
= 1.05 × 10^5 C / (1.602 × 10^-19 C/proton)
≈ 6.55 × 10^23 protons

Therefore, the mass of protons required to neutralize the charge of 1.1 g of electrons is approximately 6.55 × 10^23 protons.
