p1/p2 = T1/T2
use this formula (preesure law)to do it.. remember you need to change the unit

I don't know how to like, put everything into that formula? I'm kinda desperate right now

callisto · Answer

p = pressure in Pa
T = temperature in K

anonymous · Answer

so 780/27ºC?

callisto · Answer

yup but you need to change the unit!!!
27 deg.Cel. = 27+273 K
for the pressure, sorry, i dunno you'd better check how to convert mm Hg into Pa
