hammer [34]
 <span>Use the Ideal law Equation :

P.V= n.R.T 

V = 0.5 L

P = 1.0 atm

</span><span>R= 0.0821 L*atm/mol*K 
</span>
<span>n = R*T/P*V 

</span><span>P*V= n*R*T

Convert 338 L at 63.0 atm to its new volume at standard pressure.
taurus [48]

The new volume at standard pressure of 1 atm is 21294 liters.

Explanation:

Data given:

Initial volume of the gas V1 = 338 liters

initial pressure on the gas P1 = 63 atm

standard pressure as P2 = 1 atm

Final volume at standard pressure V2 =?

The data given shows that Boyle's law equation is to used:

P1V1 = P2V2

rearranging the equation to calculate V2,

V2 = \frac{P1V1}{P2}

Putting the values in the equation:

V2 = \frac{338X63}{1}

     = 21294 L

as the pressure on the gas is reduced to 1 atm the volume of the gas increased incredibly to 21294 litres.
