A sample of fluorine gas has a volume of 5.30 L at 15°C and standard pressure. What will be the pressure in atm if the moles of gas and the temperature do not change but the volume is expanded to 9.54 L?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
