A gas of 2.00 dm3 is at 100 kPa and 300 K. How many moles does it contain? (R = 8.31 J K-1 mol-1)
Answer and explanation
Correct answer: C. 0.0802 mol
- Step 1: Convert units: Pa and m3. Step 2. . Answer: 0.0802 mol. Why not the others: 0.0802 kmol is the same quantity written with the wrong unit; 80.2 mol and 0.802 mol come from forgetting to convert dm3 to m3 or kPa to Pa.
