This video tutorial explains how to convert 46.22 grams of nitrogen gas into liters through a two-step process. First, the grams are converted to moles by dividing by the molar mass of nitrogen. Then, the moles are converted to liters using the standard temperature and pressure (STP) conversion factor of 22.4 liters per mole. The video provides a detailed walkthrough of each step, ensuring a clear understanding of the conversion process.
