2 moles of a gas have a pressure of 2 atm at a temperature of 300 K. What is the volume of the gas?

qwelly [4]

No of moles=2mol=n
Pressure=2atm=P
Temperature=300K=T
Volume=V

$\\ \tt\hookrightarrow PV=nRT$

$\\ \tt\hookrightarrow V=\dfrac{nRT}{P}$

$\\ \tt\hookrightarrow V=\dfrac{2(8.314)(300)}{2}$

$\\ \tt\hookrightarrow V=8.314(300)$

$\\ \tt\hookrightarrow V=2494.2mL$

$\\ \tt\hookrightarrow V=24.94dm^3$

Answer:

$V=162L$

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:

$V=\frac{nRT}{P}= \frac{4.70mol*0.082\frac{atm*L}{mol*K}*(21+273)K}{0.700atm} \\\\V=162L$

Best regards.
