Question
A reaction produces 2 moles of gas A. Calculate the volume of gas A at room temperature and pressure.
Answer
48 dm3
Explanation
The answer is strong because it correctly applies the relationship that one mole of gas occupies 24 dm3 at room temperature and pressure. The question tests the understanding of gas volumes in relation to moles.
Common mistake
Incorrect Volume Calculation
Students often forget to convert volumes from cm3 to dm3 when calculating gas volumes.
Always convert cm3 to dm3 by dividing by 1000 before using the volume in calculations.
