Atomic Mass (g/mol)=Actual Mass of One Atom (amu)×Avogadro's NumberThis means that the atomic mass of an element in grams per mole is equal to the actual mass of a single atom in amu multiplied by Avogadro's number. Step 4: Example with CarbonFor carbon:- The atomic mass of ...
The atomic number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the ...

The mass of a single atom of an element (in AMU) is numerically equal to the mass in grams of 1 mole of that element. a. True. b. False. True or false? To convert from grams to moles and vice versa, you should use molar mass as a conversion factor. ...
How many protons are in a lithium atom? What is lithium chloride's formula? 1 mole of lithium (Li) is equal to how many atoms of lithium? How many atoms are in lithium hydroxide? What is the mass number of radium? What is the most common isotope of lithium?
12 standard. One unifiedatomic mass unit(u) is equal to 1/12 the mass of a carbon-12 atom — carbon-12 weighs 12 u. The mole is defined this way purely for convenience. Mathematically, it means that the mass of one mole of a compound in grams is equal to its molecular mass in u...
an atom’s valence is equal to the number of electrons in the outer shell when that number is four or fewer. then the valence in the outer shell is equal to eight minus the number of electrons. once you are aware of the number of electrons you can calculate the valence easily. test ...
One mole is a scientific form of measurement in chemistry. Elements need to have equal amounts of protons and electrons to be stable, but they can vary in the amount of neutrons they contain. The amount of protons in the element is theatomic number. ...
