9.1 x 10-31 kg
Any number that is very large, or very small (near zero). For example, the mass of the Sun in kilograms (large), the distance to the M31 galaxy in meters (large), or the mass of the electron in kilograms (small).
Mass of ten 12 kilograms = 10*12 = 120 kilograms
Kilograms.
The mass of a dime is approximately 2.268 grams, which is equivalent to 0.002268 kilograms. Therefore, while a dime's mass is not one kilogram, it can be expressed in kilograms by converting the grams to kilograms.
That depends on where you weigh 142 pounds.-- If you weigh 142 pounds on Earth, then your mass is 64.4 kilograms. (rounded)-- If you weigh 142 pounds on the Moon, then your mass is 389.2 kilograms. (rounded)-- If you weigh 142 pounds on Mars, then your mass is 169 kilograms. (rounded)-- If you weigh 142 pounds on Jupiter, then your mass is 24.4 kilograms. (rounded)...etc.
electron mass = 9.10938188 × 10-31 kilograms
The rest mass of the electron is approximately 9.11 x 10-31 kilograms.
electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
The mass of an electron is approximately 9.11 x 10^-31 kilograms. In comparison, a hydrogen atom, which consists of one proton and one electron, has a mass of about 1.67 x 10^-27 kilograms. This means that the mass of the electron is roughly 1/1836 of the mass of the hydrogen atom, making the electron's mass negligible in comparison to the proton's mass within the hydrogen atom.
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
The charge of an electron is -1. Specifically, it is about -1.602 x 10-19 coulombs. The mass of an electron is about 9.109 x 10-31 kilograms, or about one 1836th that of a proton.
The mass of an electron is approximately 9.109 x 10^-31 kilograms.
They have mass, it is just too little in comparison to the mass of the neutron and protons to be taken into account. Therefore when measuring the mass of an atom, the mass of the electron are not used. (To be exact,9.10938188 × 10-31 kilograms, and the mass of proton is 1.67262158 × 10-27 kilograms.)
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
The mass of an electron is approximately 9.11 x 10^-31 kilograms, which is significantly lighter than the mass of a proton or neutron. This implies that electrons contribute minimally to the overall mass of an atom.
