Question

How many grams of ethane (C2H6) are there in 100 L of this gas at 80 degree celsius and 25atm

Answer 1

Answer: 2588 grams of ethane are there in 100 L of this gas at 80 degree celsius and 25 atm.

Step-by-step explanation:

According to the ideal gas equation:'

`PV=nRT`

P = Pressure of the gas = 25 atm

V= Volume of the gas = 100 L

T= Temperature of the gas = 80°C = (80+273)K=353 K (0°C = 273 K)

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas= ?

`n=(PV)/(RT)=(25* 100)/(0.0821* 353)=86.3moles`

Mass of gas=
`moles* {molar mass}}=86.3* 30=2588g`

Thus 2588 grams of ethane are there in 100 L of this gas at 80 degree celsius and 25 atm.
