PLEASE ANSWER ASAP AND SHOW WORK: A camping stove uses a 5.0 L propane tank that holds 68.0 moles of liquid C3H8. How large a container would be needed to hold the same amount pf propane as a gas at 25.0 ⁰C and a pressure of 3.0 atm?​

Respuesta :

Answer: The volume of the container needed is 554.6 L

Explanation:

To calculate the volume of the gas, we use the equation given by ideal gas which follows:

[tex]PV=nRT[/tex]

where,

P = pressure of the gas = 3.0 atm

V = Volume of the gas = ? L

T = Temperature of the gas = [tex]25^oC=[25+273]K=298K[/tex]

R = Gas constant = [tex]0.0821\text{ L.atm }mol^{-1}K^{-1}[/tex]

n = number of moles of propane gas = 68.0 moles

Putting values in above equation, we get:

[tex]3.0atm\times ?L=68mol\times 0.0821\text{ L.atm }mol^{-1}K^{-1}\times 298K\\\\V=\frac{68\times 0.0821\times 298}{3.0}=554.6L[/tex]

Hence, the volume of the container needed is 554.6 L

The volume of the container needed is 554.6 L

 

To compute the volume of the gas, we use the ideal gas equation, which is as follows:

[tex]PV=nRT[/tex]   ....(1)

Here,

P = pressure of the gas = 3.0 atm

V = Volume of the gas = ? L

T = Temperature of the gas =25° C=(25+273)K=298 K

R = Gas constant = 0.0821 Latm/molK

n = number of moles of propane gas = 68.0 moles

Substitute all the values in the equation (1) as follows:-

[tex]3\ atm\times V=68\ mol\times0.0821\ Latm/Kmol\times 298\ K\\\\V=\frac{68\ mol\times0.0821\ Latm/Kmol\times 298\ K}{3.0\ atm}\\\\= 554.6\ L[/tex]

Hence, the volume of the container needed  to hold the same amount of propane is 554.6 L
