Question

A balloon is floating around outside your window. The temperature outside is 21 ∘C , and the air pressure is 0.700 atm . Your neighbor, who released the balloon, tells you that he filled it with 4.70 moles of gas. What is the volume of gas inside this balloon?

Answer 1

`V=162L`

Step-by-step explanation:

Hello,

In this case, we can compute the required volume by using the ideal gas equation as shown below:

`PV=nRT`

Thus, solving for the volume and considering absolute temperature (in Kelvins), we obtain:

`V=(nRT)/(P)= (4.70mol*0.082(atm*L)/(mol*K)*(21+273)K)/(0.700atm) \\\\V=162L`

Best regards.
