Atomic mass, molar mass, grams, # of atoms

Practice these concepts

molar mass of compounds

atomic number x number of elements

unit for molar mass of compounds

g/moL

molar mass of singular element

atomic number

unit for molar mass of singular element

u

atomic mass of 1 element

atomic mass x percent abundance

atomic mass of compounds

number of moles x molecular mass of all the elements added

unit for atomic mass

amu

grams > moles

moles = grams/molar mass

moles > grams

moles x molar mass

moles > # of atoms

number of moles x 6.022 × 10²³ atoms/moles

number of atoms > moles

number of atoms / 6.022 × 10²³

grams > number of atoms

1. molar mass ‘

2. number of moles

3. # of atoms/molecules

4. determine total atoms (if applicable)

number of atoms > grams

1. # of atoms > moles

2. moles > grams
