Answer to Question #19789 in Organic Chemistry for Brianna Dunmore

Question

Identify of an alkane gas that has a density of 1.16 g/l measured at pressure of 0.984 atm and temperature of 37C?

Answer 1

PV = nRT
n = PV/RT
n = m/M_w
m/M_w = PV/RT
M_w = mRT/PV = 1.16*8.31*(273+37)/(1*(101.3*0.984) = 30

C_xH_y

30/12=2..... x=2
30-2*12=6 y=6

Answer: C₂H₆
