Question

How many moles are in 3.01*10^23 atoms of Mg

Answer 1

0.5 mol Mg

Step-by-step explanation:

1 mole is equal to 6.02x10²³ atoms, however, we don't know how many moles equal 3.01x10²³ atoms.

mol = ( 3.01x10²³ ) * 1 / 6.02x10²³

= 0.5

Answer 2

1 mole ------------ 6.02x10²³ atoms
? moles ----------- 3.01x10²³ atoms

moles = ( 3.01x10²³ ) x 1 / 6.02x10²³

=> 0.5 moles Mg
