Calculation of Percentage Purity of Zinc Metal
Given Data:
- Mass of zinc oxide produced = 244 g
- Mass of sample containing zinc metal = 261 g
Step 1: Calculate the molar mass of ZnO
- Molar mass of Zn = 65.38 g/mol
- Molar mass of O = 16.00 g/mol
- Molar mass of ZnO = 65.38 + 16.00 = 81.38 g/mol
Step 2: Calculate the moles of ZnO produced
- Moles of ZnO = Mass of ZnO produced / Molar mass of ZnO
- Moles of ZnO = 244 g / 81.38 g/mol ≈ 3 moles
Step 3: Calculate the moles of Zn in the sample
- Since ZnO is produced by the combustion of zinc metal with oxygen, the moles of ZnO produced are equal to the moles of Zn in the sample.
Step 4: Calculate the mass of Zn in the sample
- Mass of Zn in the sample = Moles of Zn × Molar mass of Zn
- Mass of Zn in the sample = 3 moles × 65.38 g/mol ≈ 196.14 g
Step 5: Calculate the percentage purity of zinc metal
- Percentage purity = (Mass of pure Zn / Mass of sample) × 100
- Percentage purity = (196.14 g / 261 g) × 100 ≈ 75.17%
Therefore, the percentage purity of zinc metal in the sample is approximately 75.17%.
