How many moles of sodium (na) do you have in a sample of 9.8 × 10^23 atoms na?
0.61 mol na
1.6 mol na
5.9 mol na
16.3 mol na

1 mol 6.02 x 10²³ atoms Na
( mols Na) 9.8 x 10²³ atoms Na

( mols Na ) = ( 9.8 x 10²³ ) x 1 / 6.02 x 10²³

( mols Na) = 9.8 x 10²³ / 6.02 x 10²³

= 1.6 mols Na

hope this helps!

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2
