A common factor used in such calculations is one that can convert atomic mass units (u) to units of the eV. The conversion factor is found using Einstein's equation to convert the mass of 1 u to energy or [2.7]E=m0c2 where E is energy in joules, m0 is the rest mass in kilograms...
what is the mass of hydrogen in terms of amu? a) 1.0020 amu b) 1.0180 amu c) 1.0070 amu d) 1.0080 amu answer: d) 1.0080 amu explanation: the mass of a hydrogen atom is 1.6736×10 -24 g. when converted in terms of amu, 1.6736×10 -24 g should be divided by 1.66056×10 -24 ...
The mass of the nucleus can be approximated by subtracting the sum of the masses of the electrons from the atomic mass. The mass of an electron is 0.000549 u. In kilograms, this mass is 9.1094 × 10−31. Since the neutral carbon atom has 6 electrons, the approximate mass of the nucle...
If the atomic mass of an element is X, what is the mass in grams of 6.02 times 10^{23} atoms of the element? If 3 moles of an element have a mass of 222.0 g, what is the mass of 1 atom? Typically, the mass of an atom of an element in grams is closest to: a. 1023 b. ...
An atomic mass unit is defined as 1/12 the mass of a carbon-12 atom. A carbon-12 atom has 6 protons and 6 neutrons. Therefore, each proton and neutron is approximately 1 AMU. How do you convert AMU to kg? In order to convert atomic mass units to kilograms, the conversion must be...
The mass of one atom ofhydrogen-1 = 1.007 AMU The mass of one atom of titin (the largest known protein) = 3 x 106AMU Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a ne...

An atom is considered as the smallest particle of a chemical element that is existing in nature. All substances are made up of either neutral atoms or ionized atoms. The atoms of all elements have three subatomic particles i.e., electrons, protons, and neutrons....
In the overall reaction, there were one atom of carbon, four atoms of oxygen, and four atoms of hydrogen at the start of the reaction and they remain the same at the end of the reaction. Let’s understand through reaction −CH4+2O2→CO2+2H2OCH4+2O2→CO2+2H2OIn this reaction, the...
A tonne is defined as 1000 kilograms. An electron mass is defined as 9.1093897×10−28 gram. An atomic mass unit is defined as 112 the mass of the carbon-12 atom, or approximately 1.6605402×10−27 kilogram. An avoirdupois, troy, or apothecary grain is defined as 0.00006479891000 kilogr...
