What mass of protons would be required to just neutralize the charge of 2.7 g of electrons?
find the number of electrons: 2.7g/masselectron
then the mass of protons=number*massproton
the approximate answer is 2.7*1760
What mass of protons would be required to just neutralize the charge of 4.4g of electrons?
7,744
To determine the mass of protons required to neutralize the charge of electrons, we need to consider the charge of each particle.
The charge of an electron is -1.6 x 10^-19 coulombs, while the charge of a proton is +1.6 x 10^-19 coulombs (since they have equal magnitude but opposite signs). Coulombs is a unit of charge.
Now, we can calculate the number of electrons in 2.7 g of electrons using the formula:
Number of electrons = Mass of electrons / Mass of a single electron
The mass of a single electron is approximately 9.1 x 10^-31 kg.
Number of electrons = 2.7 g / (9.1 x 10^-31 kg)
Next, we can calculate the charge of the electrons:
Charge of electrons = Number of electrons x charge of a single electron
Finally, we need to determine the mass of protons required to neutralize this charge.
To do that, we need to find the number of protons with the same magnitude of charge as the electrons (since they have opposite signs). Therefore, the mass of protons required would be:
Mass of protons = Charge of electrons / charge of a single proton
The charge of a single proton is +1.6 x 10^-19 coulombs.
Mass of protons = Charge of electrons / (1.6 x 10^-19 coulombs)
