What is the best example of the purpose of scientific notation?
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).
What is the mass of ten 12 kilogram?
Mass of ten 12 kilograms = 10*12 = 120 kilograms
The mass of a human is heart is 1.05 grams or kilograms?
Kilograms.
What is your mass in kilograms if you weigh 142 pounds?
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.
Is kilograms mass?
Yes
What is the total mass of a electron in a atom?
electron mass = 9.10938188 × 10-31 kilograms
What is the atomic mass or weight of an electron?
electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
What is the mass of 1 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
Why electrons have no mass?
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.)
What is the charge and mass of a electron?
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.
Which has a greater mass an electron or a proton?
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.
Is the mass of one electron equal the the mass of one atomic mass unit?
Since "amu" stands for "atomic mass unit" ... maybe. "mass unit" is kind of a meaningless phrase; it could refer to grams, kilograms, slugs, or whatever.
Does a electron have a smaller mass than protons?
Absolutely; a proton weighs approximately 2000 times more than an electron.
What is the best example of the purpose of scientific notation?
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).
A child, a computer, and a bookshelf have combined mass of 36 kilograms. The child has a mass of 25 kilograms, and the computer has a mass of 2 kilograms. What is the mass of the bookshelf?
9 kilograms
How many electrons would add up to a mass of 1 kilo gram?
1kg divided by the mass of an electron (9.10938188 × 10-31 kilograms) equals the number of electrons per kilogram, or just one over the mass per kg of an electron. 109776932526622761367865719556.37 electrons/kg
What is the mass and charge of beta particle?
Beta particles are actually electrons (-e) or can be positrons.The mass of one electron or beta particle is 9.1095*10-31 kilograms or 0.000548597 AMU which is about 1/2000 times the mass of a proton or neutron.
