Question

13. An aerosol spray can of deodorant with a volume of 0.410 L contains 3.0 g of propane gas (CH3) as propellant. What is the pressure in the can at 20°C? VRT 3. og festa​

Answer 1

Answer: The pressure in the can is 4.0 atm

Step-by-step explanation:

According to ideal gas equation:

`PV=nRT`

P = pressure of gas = ?

V = Volume of gas = 0.410 L

n = number of moles =
`\frac{\text {given mass}}{\text {Molar mass}}=(3.0g)/(44.1g/mol)=0.068mol`

R = gas constant =
`0.0821Latm/Kmol`

T =temperature =
`20^0C=(20+273)K=293K`

`P=(nRT)/(V)`

`P=\frac0.068mol* 0.0820 L atm/K mol* 293K}{0.410L}=4.0atm`

Thus the pressure in the can is 4.0 atm
