the idea gas law formula is
PV = nRT
on this one you want to solve for the number of moles (n) using
n = PV / RT
plugging in the values for this scenario that yields
n = (0.77 atm * 6.6 L) / (0.08206 L*atm / mol*K * 302K) = 0.205 mol
meaning that you would need 0.205 moles of helium to meet these criteria

use PV=nRT where moles is n
