Mole Conversions
Problem:
3.80 mol Li = ____________ atoms Li.
moles = grams/molar mass.
So would the molar mass be 3.80? How do you get the grams?
To convert from moles to atoms, you will need to use Avogadro's number, which is approximately 6.022 x 10^23.
Avogadro's number tells us the number of atoms or molecules in one mole of a substance.
To solve the problem, you can use the following conversion factor:
1 mol Li = 6.022 x 10^23 atoms Li
Now, let's set up the conversion:
3.80 mol Li × (6.022 x 10^23 atoms Li / 1 mol Li)
By multiplying the given value (3.80 mol Li) by the conversion factor, we can cancel out the units of moles and end up with the answer in atoms:
3.80 mol Li × (6.022 x 10^23 atoms Li / 1 mol Li) = 2.29 x 10^24 atoms Li
Therefore, 3.80 mol Li is equal to 2.29 x 10^24 atoms Li.
