Answer:
212°F , 100°C , 373.15°K
They are all the same, in different units.
Try googleing it that is how i got some of mine
Increase in heat, molecules start to escape and it turns to vapor
From ideal gas equation that is PV=nRT
n(number of moles)=PV/RT
P=760 torr
V=4.50L
R(gas constant =62.363667torr/l/mol
T=273 +273=298k
n is therefore (760torr x4.50L) /62.36367 torr/L/mol x298k =0.184moles
the molar mass of NO2 is 46 therefore density= 0.184 x 46=8.464g/l
17 protons 17 electrons 18 neutrons
