NaSO4, if it could exist, would have a mass of 119.046 AMU. However, it cannot exist because the valencies do not agree.
The same way you calculate the atomic mass of other elements.
To find the number of molecules in 450 grams of NaSO4, we first need to calculate the number of moles using the molar mass of NaSO4 (142.04 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in the calculated moles.
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
Atomic mass - Atomic number
To calculate the atomic mass of an element, you multiply the mass of each isotope by its relative abundance, then add the results together.
The atomic mass of Mg is 24.3 amu.
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
the atomic mass number is the number of protons/electrons in an atom
NaSo4
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
