How many moles in 67.8 g of F2 ( Fluorine compound)?

Sagot :

Answer:

1.78 moles

Explanation:

to find moles, use the formula moles=mass/rfm

the rfm is the mass number (the bigger number) on the element's square thingy on the periodic table

the mass number of fluorine is 19

19*2 (because it's diatomic you multiply it by 2) =38

so 67.8/38=1.78421052632

round it to 2 sf= 1.78 moles
