Question #74407

calculate the mass of chlorine gas contained in a 5.00dm^3 flask at 25°C and 98 kPa pressure

Expert's answer

According to ideal gas law:

m/M×RT=PV

Find the mass:

m = (M×P×V)/(R×T)

V = 0.005 m3

T = 298 K

P = 98000 Pa

R = 8.314 J×mol-1×K-1

M = 71 g×mol-1

m = (71×98000×0.005)/(298×8.314) = 14.04 (g)

m/M×RT=PV

Find the mass:

m = (M×P×V)/(R×T)

V = 0.005 m3

T = 298 K

P = 98000 Pa

R = 8.314 J×mol-1×K-1

M = 71 g×mol-1

m = (71×98000×0.005)/(298×8.314) = 14.04 (g)
