Percentage Composition of a Compound
To calculate the percentage composition of a compound, we need to determine the mass of each element present in the compound and then express it as a percentage of the total mass of the compound.
Given:
- Mass of the compound = 0.24 g
- Mass of boron in the compound = 0.096 g
- Mass of oxygen in the compound = 0.144 g
Step 1: Calculate the Percentage of Boron
To find the percentage of boron in the compound, we divide the mass of boron by the mass of the compound and multiply by 100.
Percentage of boron = (Mass of boron / Mass of compound) * 100
= (0.096 g / 0.24 g) * 100
= 40%
Step 2: Calculate the Percentage of Oxygen
To find the percentage of oxygen in the compound, we divide the mass of oxygen by the mass of the compound and multiply by 100.
Percentage of oxygen = (Mass of oxygen / Mass of compound) * 100
= (0.144 g / 0.24 g) * 100
= 60%
Step 3: Summarize the Results
The percentage composition of the compound by weight is as follows:
- Boron: 40%
- Oxygen: 60%
Conclusion
The compound consists of 40% boron and 60% oxygen by weight. This means that for every 100 grams of the compound, there are 40 grams of boron and 60 grams of oxygen.

= 40%
Step 2: Calculate the Percentage of Oxygen
To find the percentage of oxygen in the compound, we divide the mass of oxygen by the mass of the compound and multiply by 100.
Percentage of oxygen = (Mass of oxygen / Mass of compound) * 100
= (0.144 g / 0.24 g) * 100
= 60%
