What is the maximum amount of oxygen difluoride that can be produced when 0.55 mol of oxygen reacts with .90 mol of fluorine? Please show work
The balanced chemical reaction is:
2 F2 + O2 —> 2 OF2
2 mol of F2 reacts with 1 mol of O2
so,
0.55 mol of O2 requires 0.55*2 = 1.10 mol of F2
But we have only 0.90 mol of F2
so,
F2 is limiting reagent
we will use F2 in our further calculations
Form balanced chemical reaction
mol of OF2 formed = mol of F2 reacted
= 0.90 mol
Molar mass of OF2,
MM = 1*MM(O) + 2*MM(F)
= 1*16.0 + 2*19.0
= 54 g/mol
mass of OF2,
m = number of mol * molar mass
= 0.9 mol * 54 g/mol
= 48.6 g
Answer: 48.6 g
