Question

A 25 liter gas cylinder contains 10 mole of carbon dioxide. Calculate the pressure, in atm, of the gas at 325K.

Answer 1

Answer: The pressure of carbon dioxide gas is 11 atm

Step-by-step explanation:

To calculate the pressure of gas, we use the equation given by ideal gas equation:

PV = nRT

where,

P = pressure of the gas = ?

V = Volume of gas = 25 L

n = number of moles of gas = 10 mole

R = Gas constant =
`0.0821\text{ L atm }mol^(-1)K^(-1)`

T = temperature of the gas = 325 K

Putting values in above equation, we get:

`P* 25L=10mol* 0.0821\text{ L atm }mol^(-1)K^(-1)* 325K\\\\P=11atm`

Hence, the pressure of carbon dioxide gas is 11 atm
