Question

3rd attempt id See Periodic Table See Hint A sample of a gas weighs 2.05g and has a volume of 956.0 mL at 685.0 torr and 40.0

Answer 1

Answer #1

m = 2.05 gm

V = 956 mL = 0.956 L

T = 40^o C = 313 K

P = 685 torr = 685/760 = 0.901 atm

R= 0.08206 L⋅atm /K⋅mol

n = PV/ RT = 0.03353 mol

molar mass = 2.05 gm / 0.03353 mol = 61 gm / mol
