Twenty (20.0) mL of argon gas (Ar) is stored at STP. If the temperature and pressure are both doubled, what is the new volume? PLZZ ANSWER ASAP!!

The new volume is the same as the initial volume, i.e. 20 mL.

Explanation:

To find the new volume we can use the Ideal gas law:

Where:

P: is the pressure

V: is the volume

R: is the gas constant

n: is the number of moles

T: is the temperature

Initially, we have:

   (1)

In the final state:  

   (2)

By equating equation (1) and (2) we have:          

Therefore, the new volume is the same as the initial volume, i.e. 20 mL.

I hope it helps you!
