Question

Oxygen difluoride is a hazardous, highly explosive gas used as a propellant. A sample of this compound weighing 0.432 grams is analyzed. It contains .128 grams of oxygen. What is the percentage composition of oxygen and fluorine in this compound ? (Show work)

Answer 1

Answer:

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = 70.37

Explanation:

Given:

Mass of compound = 0.432 grams

Mass of oxygen = 0.128 grams

Find:

Percentage composition of oxygen

Percentage composition of fluorine

Computation:

Percentage composition of oxygen = [0.128/0.432]100

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = [(0.432 - 0.128)/0.432]100

Percentage composition of fluorine = 70.37
