Calculating the Magnitude of Total Negative Charge on Electrons in Helium

What is the magnitude of the total negative charge on the electrons in 1.32 mol of helium?

The magnitude of the total negative charge on the electrons in 1.32 mol of helium is 1.27232 x 10^5 C.

Understanding the Magnitude of Total Negative Charge

The magnitude of the total negative charge refers to the total amount of negative charge present in a system or object. In the case of 1.32 mol of helium, we are looking to determine the total negative charge carried by all the electrons in this amount of helium.

In order to calculate the magnitude of the total negative charge on the electrons in 1.32 mol of helium, we need to follow a few steps:

  • Firstly, calculate the total number of electrons by multiplying Avogadro's number (6.022 x 10^23 electrons/mol) by the number of moles of helium (1.32).
  • This gives us a total of 7.952 x 10^23 electrons.
  • Next, determine the charge of a single electron, which is 1.6 x 10^-19 C (Coulombs).
  • Finally, multiply the total number of electrons by the charge of a single electron to find the magnitude of the total negative charge.
  • Multiplying 7.952 x 10^23 electrons by 1.6 x 10^-19 C/electron gives us 1.27232 x 10^5 C.

Therefore, the magnitude of the total negative charge on the electrons in 1.32 mol of helium is calculated to be 1.27232 x 10^5 C, representing the cumulative charge carried by all the electrons present in the given amount of helium.
