What mass of protons would be required to just neutralize the charge of 1.0g of electrons?

Answer 1

1 proton would neutralize 1 electron. According to wikipedia, "An electron has a mass that is approximately 1/1836 that of the proton." so you'd need 1836/1 fold the mass of electrons, or in this case 1,836g of protons.

Answer 2

electron mass = 9.10938188 × 10-31 kilograms

proton mass = 1.67262158 × 10-27 kilograms

Get the ratio of proton mass/electron mass.

1.8 X 103 gm

Answer 3

One electron is required to neutralize one proton. The rest mass of an electron is about 0.91095 X 10-30 kg and the rest mass of a protons is about 1.6726 X 10-27 kg. Therefore, 3.9 grams of protons would be neutralized by 3.9 (0.91095 X 10-30 /1.6726 X 10-27) or 2.1 X 10-3 grams of electrons, to the justified number of significant digits.

Answer 4

1/1836 gram.As you know, both proton and electron has equal but apposite charge. But then, if you take there mass then 1836 electrons make one proton. So if we take 1 gram of protons we will require 1/1836 gram of electrons. Alternately if we take 1 gm of electrons, you will have to take 1836 grams of protons.

Answer 5

To two significant figures, 1800 g or 1.8 kg.

Answer 6

What mass of electrons would be required to just neutralize the charge of 1.2g of protons?

Answer 7

the mass of an electron 0.00054 that of the proton. so yo would need only

3.1 X 0.00054 = 0.001674 g
