The equation for the amount of gas in moles at room temperature and pressure (RTP) is n=V[...]n = \frac{V}{\text{[...]}}n=[...]V when VVV is in dm3\text{dm}^3dm3.
The equation for the amount of gas in moles at room temperature and pressure (RTP) is n=V24.0n = \frac{V}{\boxed{24.0}}n=24.0V when VVV is in dm3\text{dm}^3dm3.
