Question

How many grams of ethane gas (C2H6) are in a 12.7 liter sample at 1.6 atmospheres and 24°C? Show all work used to solve this problem.

Answer 1

Last question! Here's my answer:

n = PV/RT
P = 1.6 atm
V = 12.7 L
R = 0.0821
T = 24 degrees C ----> 297.15 degrees K
n = (1.6 * 12.7) / (0.0821 * 297.15)
n = 20.32 / 24.39
n = 0.83 mol
C = 12.010
H = 1.0079
C2 = 12.010 * 2 = 24.02
H6 = 1.0079 * 6 = 6.0474
C2H6 = 30.0674
30.0674 * 0.83 = 24.95 grams (C2H6)
