What is the mass of a proton in AMU?Atomic Mass UnitAMU or the atomic mass unit is 1/12 the mass of carbon-12, which is made up of 6 protons and 6 neutrons. It is also defined more loosely as the mass of the total number of protons and neutrons in an atom's nucleus. It is ...
This unit is use to describe the actual mass of an atom or compound. It differs than molar mass because molar mass assumes Avogadro's number of atoms or molecules in the sample while amu is the mass of a single atom or molecule.Answer and Explanation: There is 12.011 amu o...

What is the mass of 1 mole of a raindrop?Mole:The Mole is a unit that represents a certain number. It is defined as the number of carbon atoms contained in a pure sample carbon-12 of mass {eq}12\;\rm g {/eq}. The constant number of called the Avogadro's constant. The order o...
The mass of carbon is 12 atomic mass units (AMU), with a relative abundance of 2.1%. It can be found pure in natural resources or synthesized. Carbon has two stable isotopes: C and C. Flash memory cards contain pure graphite mixed with impurities to create resistive SOI layers on silicon...
What mass of carbon has the same number of atoms as 78.54 grams of chromium? Molar Mass The molar mass of an atom or a compound is the mass of one mole of that compound. The molar mass of the atom or compound can be used as a conversion factor to convert the mass of th...
It is 1.992648 xx 10^(-23) g ~~ 1.99 xx 10^(-23)g It can be obtained by dividing gram atomic mass of carbon (12 g) with Avogadro's No. (N(A)) ((12g))/(6.022xx10^(23))~~1.99xx10^(-23)g.
D12 gSubmit Assertion : One atomic mass unit is defined as one twelfth of the mass of one C-12 atom. Reason : C-12 is the least abundant isotope of carbon and has been choosen as the standard. AIf both assertion and reason are true and reason is the correct explanation of asserti...
12. On Earth, carbon-12 accounts for almost 99 percent of naturally occurring carbon. Scientists use atomic mass units, or amu, to measure the mass of elements. Carbon-12 has an amu of exactly 12.000. This number is the reference standard for measuring the atomic mass of all other ...
Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it's more correct to call the value "relative molecular mass". A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. ...
