Determining the molar volume of a gas lab
WebFormal Lab Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂ (g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂ (g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the ... WebThis volume is called the molar volume.
