8
Q
molar gas volume
A
1 mole of any gas at room pressure (1 atm) and room temperature 25C will have the volume of 24dm3

A
volume (dm^3) = mol x 24
10
Q
Potential errors in using a gas syringe
A
Gas escapes before bung inserted
Syringe sticks
Some gases like CO2 & SO2 are soluble in water so the true amount of gas is not measured
