Part of the atom that contains protons and neutrons is called?
Surely it's just a nucleus, as every version of an element is an isotope in its own right, and the atomic and molar masses are just an average made by relative abundance...hope this helps.
8. On most periodic tables a single atomic mass is listed instead of the mass numbers for all the stable isotopes. How is this mass related to the different isotopes?
In a normal periodic table, the molar mass of a given element, is made up of multiplying the mass of a given isotope of that element, with the abundance of that given isotope in percent. For example, Say for the element X, you know that it has two isotopes, X12 and X13. X12 has a molar mass of 12 g/mol, and you know that of all the X molecules in the world, X12 is found 95% of the time, X13 has a molar mass of 13g/mol, yet its abundence is only 5%. Therefore average molar mass for element X is calculated as such, (12 * .95)+(13*.05) = 12.05 g/mol. hope that helps.
How do you find molar mass of anhydrous sodium carbonate when given the molar mass of hydrated sodium carbonate?
Add up the atomic masses of its constituent elements in their respective proportions, giving you a value of 105.988 g mol-1.
What is the relationship between the molar mass and atomic mass?
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams.The atomic mass is the mass of an isotope expressed in unified mass atomic units.The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
Is the molar mass a fixed quantity for a particular substance?
For most purposes, the molar mass of any particular substance remains the same. However to be precise I will note that there are isotopic variations which can affect molar mass. In other words, it is normally expected that a given substance will have a certain mixture of isotopes giving a certain mass, but a substance obtained from one source might have a different isotope ratio than the same substance obtained from a different source.

What is the difference in molar mass and atomic mass?
molar mass is the actual mass of the one atom but relative mass is the average isotopes of the atoms.------------------------------------------Atomic mass is the mass of an isotope, expressed in atomic mass units.Molar mass is the mass of molecule, calculated from the atomic weights of the contained chemical atoms, expressed in grams.
What is the difference between fluxs J and N in mass transfer?
N is avg molar flux of constituent relative to a fixed location in space and J is molar flux of constituent relative to avg molar velocity of all constituents.
How do you calculate molar mass?
You multiply the molar mass of the component element by how many of that atom appear in one molecule. You add all the elements' masses together to get the molar mass of the molecule. For example, SO2 1 * mass of sulfur =32.1 g 2 * mass of oxygen =32.0 g 32.1 g + 32.0 g = 64.1 g

What is the two decimal places of relative atomic mass and the molar mass of the element potassium K?

What describes the number of moles of solute over the total number of moles in a solution?
This is the molar fraction.
How do you calculate the formula mass in amu?
The atomic weight (not mass) of an element is dtermined considering the isotopic composition of the element and the atomic masses of these isotopes. For the calculation see the link below.
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
What is the mole fraction of solute in a 3.30 m aqueous solution?
This is the ratio between the molar concentration of this solute and 3,3.
