The mass of a single electron is approximately (9.11 \times 10^{-31}) kilograms. Therefore, the mass of two million electrons can be calculated by multiplying the mass of one electron by two million, resulting in approximately (1.82 \times 10^{-24}) kilograms. This mass is extremely small and negligible in most practical contexts.
What else can I help you with?
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
An element's atomic mass does not include the mass of its?
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
What particles account for the charge of the mass?
Protons and electrons are particles that account for the charge of the mass. Protons have a positive charge, while electrons have a negative charge. The net charge of an object is determined by the balance of these two particles.
Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."
Does hydrogen or helium have the least atomic mass?
Hydrogen has the lowest atomic mass of all the elements. Hydrogen has one proton and one electron. Helium, two neutrons, two protons and two electrons.
What happens to the mass of an atom when it loses two electrons?
The mass become lower but the difference is not significant.
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.

What is the mass of two moles of electrons?
1.10mg or 1.008mg

What are the two particles that have a mass?
Both protons and neutrons have a mass value of one. Electrons have meass but it is 1/1870 and is usually not counted in the mass of an element.

How is it possible for two isotopes of different elements to have the same mass?
The atomic mass of an isotope is the sum of protons, neutrons and electrons masses.
How is mass related to electrons?
because the electrons plus the nuetrons equal the mass
What is the mass of 3 electrons?
depends on the electrons
What two subatomic particles are added together to calulate the atomic mass?
Protons, neutrons and electrons.
