Answer:

n=4.1mol

Explanation:

Hello,

In this case, we can use the ideal gas equation:

PV=nRT

So we know the temperature, pressure and volume, therefore we can easily compute the required moles as shown below:

n=\frac{PV}{RT}=\frac{2.0atm*101L}{0.082\frac{atm*L}{mol*K}*600K}  \\\\n=4.1mol

Best regards.
