What mass of protons would be required to just neutralize the charge of 1.5 g of electrons?

my teacher said .0015kg times 1e-/.00091e-27kg times 1pt/1e- times 1.67262e-27 over 1 p

That is what I would do also. But I think you ought to know why that is the method.

figure number electrons in 1.5g:
number electrons: .0015kg/9.11E-31

now figure the mass of the same number of protons:
1.67E-27kg*(.0015/9.11E-31)

do i add the e-27 and e-31. i forget

a^b/a^c= a^(b-c)

what? sry im not getting this...

so i got 8.087535951e20 kg. my anser is suppose to be in grams so would it be 8087.535951e17?

does this sound right/what u got?

thanks

To answer this question, we need to find the mass of protons required to neutralize the charge of the given mass of electrons. Here's how you can calculate it:

1. Determine the charge of the given mass of electrons. The charge of one electron is 1.602 x 10^-19 Coulombs, so we need to convert the mass of electrons to Coulombs.

Given mass of electrons = 1.5 g = 0.0015 kg
Charge of one electron = 1.602 x 10^-19 C

To convert the mass to Coulombs, use the equation:

Charge (C) = Mass (kg) * (1e-/0.00091e-27 kg)

Plugging in the values:

Charge (C) = 0.0015 kg * (1e-/0.00091e-27 kg)

2. Calculate the number of protons required to neutralize the charge. Since the charge of an electron is negative, we need an equal number of positive charges to neutralize it. Each proton has a charge of +1.602 x 10^-19 C, so divide the charge of the electrons by the charge of one proton:

Number of protons = Charge (C) / (1.602 x 10^-19 C)

3. Finally, calculate the mass of the required number of protons. The mass of a proton is approximately 1.67262 x 10^-27 kg, so multiply the number of protons by the mass of one proton:

Mass of protons = Number of protons * (1.67262 x 10^-27 kg)

Remember to substitute the values calculated in step 1 and step 2 into step 3, and perform the necessary calculations to find the mass of protons required to neutralize the given mass of electrons.
