give me some values of atomic mass of some elements like lithium etc plz I need many elements value
Reshminourin:
plz soon
learn the atomic numbers, you'll get a rough idea of atomic masses (it's the double of atomic number)
usually the double, it can differ.. sometimes
but u get the idea
like helium's atomic number is 2, mass number= 4
OK but what's the atomic mass of lithium
lithium atomic number= 3, mass number= 6
then it's not 7
yeah @shreya68614 is correct

lithium-
atomic mass= 6
other element like
magnesium-
atomic mass= 24
still

6.941 u is the atomic mass of lithium.
yes it's correct!
then it's 7 or 6
ok
means
7 or 6 is nothing in this because lithium's atomic mass is 3 then the configuration will be 2,1
actually the question is find the no of moles for 1.4g of lithium
wait I'll tell you
Lithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium. This is why we state the atomic and molecular masses in units of grams per mole or g/mol.
What can we do with moles? We use the unit to make calculations based on balanced chemical equations. We use the stoichiometry to make predictions about how much product will be made or reactant needed if we know one mole amount in a reaction.
