I got 27.2 g/L aswell so which answer is correct??

P = Pressure
V = Volume
T = Temp (59.0 + 273 = 332K)
n = # moles
d = n/V
R = Gas constant (.0821 L atm/mol K)
Rearranging PV=nRT you get the equation:
P/TR = n/V or P/RT = d
Plug in the numbers:
d = (1.00atm)/(.0821 L atm/mol K)(332K)
d = 27.3 L/ mol

Density Of Br2

the molar mass of Br2 = 160g
at 1atm = 101325Pa and 59°C = 59+273 =332K
the number of moles in 1m^3 is
n = pV/RT = 101325*1/8.31*332 =36.73 moles
their mass is 36.73*160 =5876g = 5.876kg
so the density is 5.876kg/m^3 = 5.876g/L

Use the eqn.
P = dRT
Thus, d = 1/(0.821*(273+59)) g/l = 3.668 mg/l
