Assuming that the gas becomes saturated with benzene vapor and that the total gas volume and temperature remain constant, what is the vapor pressure of the benzene in torr?

Respuesta :

87.07 torr

Explanation:

n:7.7059 g-5.9203 g= 1.7856 g

Molar mass of benzene = 78.11g/mol

n=1.7856 g /78.11g/mol= 0.023 mol

T= 273 + 28 = 301 K

PV=nRT.

Weget

P=nRT/V

P=(0.023 mol x 8.3 J/molK x 301 K) / 0.00495m3= 11608. 3Pa= 87. 07 Torr

Answer: 87. 07 Torr
