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 a

Lady_Fox [76]

Answer:

$n = 243.605$

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

$n = \frac{pV}{RT}$

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:

$n = \frac{pV}{RT}$

$n = \frac{200 * 30}{0.0821 * 300}$

$n = \frac{6000}{24.63}$

$n = 243.605$

<em>Hence, there are 243.605 moles</em>
