Answer:

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = 70.37

Step-by-step 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
