The video tutorial explains how to convert liters of argon gas to moles. It introduces a mnemonic to remember the conversion process: multiply by 22.4 liters per mole when converting moles to liters, and divide by 22.4 when converting liters to moles. The tutorial provides a step-by-step calculation example using 9.6 liters of argon gas, resulting in 0.43 moles. It concludes with notes on standard temperature and pressure conditions and the behavior of argon as a noble gas.
