A. 60.0 dm3
B. 50.0 dm3 (A-level cue 24426dcb distractor 1)
C. 70.0 dm3 (A-level cue 24426dcb distractor 2)
D. 80.0 dm3 (A-level cue 24426dcb distractor 3)

Answer

60.0 dm3

Explanation

The correct option is 60.0 dm3. 60.0 dm3 is correct because it supports the objective: Rearrange the ideal gas equation to calculate pressure, volume, amount, gas constant or temperature where appropriate.. The reasoning stays within The ideal gas equation and avoids drifting into a similar A-Level Chemistry idea. This version is uniquely anchored to The ideal gas equation. Retrieval anchor: A-level cue 24426dcb.

Common mistake

Rearranging the Ideal Gas Equation

Students often forget to convert all values to SI units before using the ideal gas equation, leading to incorrect calculations.

Always convert pressure to Pascals (Pa), volume to cubic meters (m³), and temperature to Kelvin (K) before substituting values into the ideal gas equation (pV = nRT). For example, if given pressure in atm, convert it to Pa using the conversion 1 atm = 101325 Pa.
