Question

What are the moles of gas are in a 30 liter scuba canister if the temperature of the canister is 300 K and the pressure is 200 atmospheres?

Answer 1

`n = 243.605`

Step-by-step explanation:

Given

`Pressure, P = 200\ atm`

`Temperature, T = 300k`

`Volume, V = 30L`

Required

Calculate the number of moles

We'll apply the following formula to solve this question

`n = (pV)/(RT)`

Where

`R = 0.0821 L\ atm/(mol\ K)`

The above equation is an illustration of the ideal gas law

Substitute values for p, V, R and T in:

`n = (pV)/(RT)`

`n = (200 * 30)/(0.0821 * 300)`

`n = (6000)/(24.63)`

`n = 243.605`

Hence, there are 243.605 moles
