a sample of gas has a volume 8 liters
@ 293 degree kelvin & 700 torr what will volume be at STP?

P1V1/T1=P2V2/T2 ; basic proportion.
STP mean standard temperature and pressure
P1=700 torr V1=8 Liters T1=293K
P2=standard pressure=1 atm=760 torr V2=unknown T2=standard temperature=273K
i hope you can follow my though process.
(700*8)/293=(760*V)/273
V=6.87
